A function of NPAAC is to formulate Standards and initiate and promote education programs about pathology tests. Publications produced by NPAAC are issued as accreditation material to provide guidance to laboratories and accrediting agencies about minimum Standards considered acceptable for good laboratory practice. Failure to meet these minimum Standards may pose a risk to public health and patient safety. Scope The Requirements for Transfusion Laboratory Practice is a Tier 4 NPAAC document and must be read in conjunction with the Tier 2 document Requirements for Medical Pathology Services. The latter is the overarching document broadly outlining Standards for good medical pathology practice where the primary consideration is patient welfare, and where the needs and expectations of patients, Laboratory staff and referrers (both for pathology requests and inter-Laboratory referrals) are safely and satisfactorily met in a timely manner. Whilst there must be adherence to all the Requirements in the Tier 2 document, reference to specific Standards in that document are provided for assistance under the headings in this document. The Requirements for Transfusion Laboratory Practice is for use by transfusion Laboratory personnel for the purpose of transfusion testing and safe transfusion Laboratory practice. Current Australian and New Zealand Society of Blood Transfusion (ANZSBT)1 and National Blood Authority (NBA)2 documentation may be used for further guidance. These Requirements encompass: documentation and accurate patient identification systems to minimise clerical errors and misidentification retention of records, data and documentation red cell serology testing in the pretransfusion, antenatal and perinatal settings requirements necessary for the use of computers and computer software in transfusion Laboratory practice quality assurance and quality control programmes for reagents, techniques and personnel selection and provision of appropriate blood and blood products inventory management, storage and handling of blood and blood products investigation of adverse events associated with transfusion. There are additional requirements and recommendations that may apply in certain circumstances e.g. special requirements for blood products in defined patient groups.

Blood products means, generically in this document, manufactured fractionated plasma products. Computer crossmatching means application of computer software to perform all the validity checks required for the issue of compatible blood. Confirmatory or check group or forward group means testing of red cells for ABO and Rh(D) status using commercial reagents. External Quality means a program in which multiple Specimens are periodically sent to members of a group of Laboratories for analysis and/or Assessment In vitro diagnostic medical device (IVD) identification, in which each Laboratory’s results are compared with those of other Laboratories in the group and/or with an assigned value, and reported to the participating Laboratory and others. Such a program may also compare an individual’s results with their peer group. means a medical device test if it is a reagent, calibrator, control material, kit, Specimen receptacle, software, instrument, apparatus, equipment or system, whether used alone or in combination with other diagnostic goods for in vitro use. It must be intended by the manufacturer to be used in vitro for the examination of Specimens derived from the human body, solely or principally for the purpose of giving information about a physiological or pathological state, a congenital abnormality or to determine safety and compatibility with a potential recipient, or to monitor therapeutic measures. The definition of an IVD does not encompass products that are intended for general Laboratory use that are not manufactured, sold or presented for use specifically as an IVD. In-house IVD means an IVD that is developed de novo, or developed or modified from a published source, or developed or modified from any other source, or its intended purpose, within the confines or scope of a Laboratory or Laboratory network, and is not supplied for use outside the Laboratory or Laboratory network. Commercial IVDs being used clinically for a purpose other than that originally intended by the manufacturer are also classed as in-house IVDs and are subject to the requirements of this standard. Quality Assessment means a measurement and monitoring function of quality assurance for determining how well health care is delivered in comparison with applicable standards or acceptable bounds of care. Quality Assurance means part of quality management focused on providing confidence that quality requirements will be fulfilled. Quality control means the study of those errors that are the responsibility of the Laboratory, and the procedures used to recognise and minimise them. This study includes all errors arising within the Laboratory between the receipt of the Specimen and the dispatch of the report. On some occasions, the responsibility of the Laboratory may extend from the collection of the Specimen from the patient and the provision of a suitable container, to the dispatch and delivery of the report. Internal quality control: means processes and activities that are used within the Laboratory to monitor the day-to-day operational and analytical performance of test procedures. These activities may include on-going instrument standardisation checks, instrument maintenance, analysis of control material, statistical or graphical assessment of results from control material. Requirements for Medical Pathology Services (RMPS) means the overarching document broadly outlining standards for good medical pathology practice where the primary consideration is patient welfare, and where the needs and expectations of patients, Laboratory staff and referrers (both for pathology requests and inter-Laboratory referrals) are safely and satisfactorily met in a timely manner. The standard headings are set out below – Standard 1 – Ethical Practice Standard 2 – Governance Standard 3 – Quality Management Standard 4 – Personnel Standard 5 – Facilities and Equipment A – Premises B – Equipment Standard 6 – Request-Test-Report Cycle A – Pre-Analytical B – Analytical C – Post-Analytical Standard 7 – Quality Assurance Reverse group means testing of plasma or serum for the presence of anti-A and/or anti-B to confirm results of a forward group. Transfusion reaction means any adverse event related to the transfusion of blood component. Transfusion record means, for the purpose of this document, the patient’s Laboratory record. Introduction Transfusion medicine is an essential part of medical practice and is critical to patient care. The use of blood products and blood components provides essential therapeutic support in a broad range of medical and surgical settings, and is associated with recognised risks. The Requirements for Transfusion Laboratory Practice document is the NPAAC Standard to be used to assure the safety, quality and efficacy of transfusion testing, associated transfusion Laboratory practice, non-transfusion related blood group immunohaematology testing and for accreditation purposes and must be read in conjunction with the Tier 2 document Requirements for Medical Pathology Services. Transfusion testing includes terms specific for this area of practice, and these are defined in the ‘Definitions’ section of this document. Importantly, to assist in the interpretation of the requirements, the terms ‘blood component’ and ‘blood product’ have been used to distinguish between components produced within donor centres, and fractionated plasma derivatives. NPAAC has produced these mandatory Requirements, in conjunction with ANZSBT1, for the accreditation of transfusion Laboratories. The ANZSBT is the pre-eminent specialist society in Laboratory and clinical transfusion practice and has developed a number of guidelines in transfusion practice relevant to this document.1 Future revisions of this document will be undertaken following the usual NPAAC practice and ANZSBT Guidelines, and will also take into account initiatives from other professional, national or federal organisations including TGA, NBA, Australian Red Cross and the Australian Commission on Safety and Quality in Health Care dealing with regulatory frameworks, haemovigilance, quality use and transport of blood components and products. These Requirements are intended to serve as minimum Standards in the accreditation process and have been developed with reference to current and proposed Australian regulations and other standards from the International Organization for Standardization including: AS ISO 15189 Medical laboratories – Requirements for quality and competence These Requirements should be read within the national pathology accreditation framework in conjunction with the current version of each of the following NPAAC documents: Tier 2 Document Requirements for Medical Pathology Services All Tier 3 Documents Tier 4 Document Requirements for Procedures Related to the Collection, Processing, Storage and Issue of Human Haemopoietic Progenitor Cells In addition to these Standards, Laboratories must comply with all relevant state and territory legislation. In each section of this document, points deemed important for practice are identified as either ‘Standards’ or ‘Commentaries’. A Standard is the minimum requirement for a procedure, method, staffing resource or facility that is required before a Laboratory can attain accreditation – Standards are printed in bold type and prefaced with an ‘S’ (e.g. S2.2). The use of the word ‘must’ in each Standard within this document indicates a mandatory requirement for pathology practice. A Commentary is provided to give clarification to the Standards as well as to provide examples and guidance on interpretation. Commentaries are prefaced with a ‘C’ (e.g. C1.2) and are placed where they add the most value. Commentaries may be normative or informative depending on both the content and the context of whether they are associated with a Standard or not. Note that when comments are expanding on a Standard or referring to other legislation, they assume the same status and importance as the Standards to which they are attached. Where a Commentary contains the word ‘must’ then that Commentary is considered to be normative. Please note that Appendix A is normative and is an integral part of this document.

Patient identification and labelling (Refer to Standard 6A in Requirements for Medical Pathology Services) Accurate patient identification and Specimen labelling are crucial to patient safety. Failure to comply with these requirements remains a significant cause of patient morbidity and mortality. S1.1 The request form must include a collector declaration similar to that below, which must be signed by the person collecting the patient’s Specimen immediately following verification of patient identity at time of collection: I certify that I collected the accompanying specimen from the above patient whose identity was confirmed by enquiry and/or examination of their name band and that I labelled the specimen immediately following collection and before leaving the patient. S1.2 Where there is an electronic request, both the requestor and the collector must be identified. C1.2 (i) Where the request has been transported electronically there must be a documented protocol indicating how the patient is to be identified at the point of collection. C1.2 (ii) If there is a current pretransfusion group and screen request, verbal requests for blood group dependent blood components or blood products may be accepted. These must be documented by the Laboratory. S1.3 Specimen labelling must be correct, adequate and unambiguous. C1.3(i) The patient’s details should be handwritten on the Specimen tube. If pre-printed labels are used, they must comply with RMPS. Hand-held computers in conjunction with barcode scanners and label printers or radio-frequency identification (RFID) systems are available that facilitate secure patient identification at the time of Specimen collection. The use of such systems must be in accordance with the Specimen requirements. C1.3(ii) The label must include the date and time of collection and the collector’s name / initials. 2. Transfusion Laboratory records (Refer to Standard 6 in Requirements for Medical Pathology Services) Laboratory records S2.1 Where pretransfusion record management is computerised, the Laboratory information system must comply with NPAAC’s requirements that address information communication and retention of records. S2.2 Each patient’s Laboratory transfusion record for blood components must contain the following information Patient (recipient): (a) family name and given name(s) (b) medical record number or date of birth (c) date and time of Specimen collection and expiry date (d) ABO/Rh(D) blood group (e) antibody screen results or antibody specificity where applicable (f) antigen typings where available (g) identification of the person performing the compatibility testing. Blood component: (a) component type (b) donation/batch number (c) ABO/Rh(D) blood group (where applicable) (d) expiry date of the component (e) date and time of issue. For fractionated blood products to individual patients the record must include: (a) family name and given name(s) (b) medical record number or date of birth (c) product type (d) donation/batch number (e) expiry date of the product (f) date and time of issue. For fractionated blood products to a clinical area the record must include: (a) component type (b) donation/batch number (c) clinical area sent to (d) date and time of issue (e) expiry date of product. Compatibility record S2.3 A permanent record of each unit of blood component issued to a patient must contain the following: (a) patient’s family name and given name(s) (b) medical record number or date of birth (c) ABO/Rh(D) blood group and antibody screen of patient (d) component details including type, donation number, blood group and expiry date (e) details of any special requirements, warnings or other relevant information. Labelling S2.4 A ‘compatibility’ label must be securely attached to each blood component unit or blood product unit once pretransfusion testing (or selection) is completed and the unit is allocated to the patient. It must contain the following information: Patient (recipient): (a) family name and given name(s) (b) medical record number or date of birth (c) ABO/Rh(D) blood group. Blood component: (a) donation or batch number (b) ABO/Rh(D) blood group (c) statement of compatibility (d) identity of the person affixing the label. Inventory management S2.5 The Laboratory must have systems in place to trace every blood component or blood product which it issues, whether this is to a patient, clinical area, another facility or disposal. The Laboratory must record the following information in relation to each blood component or blood product it receives (according to national or jurisdictional policy): (a) source (b) donation or batch number (c) blood component or blood product type (d) ABO/Rh(D) group (where applicable) (e) date and time received (f) expiry date (g) recipient's family name, given name(s), medical record number or date of birth (h) date and time of issue (i) 3. the fate of the blood component or blood product (issued, recalled, expired, transferred, or discarded). Pretransfusion testing (Refer to Standard 6 in Requirements for Medical Pathology Services) S3.1 An ABO and Rh(D) group must be determined for all Specimens accepted for pretransfusion testing. C3.1 Forward and reverse groups must be performed for all Specimens for pretransfusion testing. For newborns and confirmatory groups, only the forward group is required. S3.2 When performing blood grouping, all discrepancies must be resolved (eg. with historical records). S3.3 The ABO and Rh(D) group must be confirmed before red cells are transfused by: S3.4 (a) comparing the current findings with those recorded for previous Specimens; or (b) repeating the test (manual or automated) on the same Specimen by re-testing on a separate occasion to the first test; or (c) testing a second Specimen collected separately from the original Specimen. C3.3 Where possible in manual testing, a second worker, having no prior knowledge of the initial result, should perform the second test. A reverse ABO group is not mandatory when performing this confirmatory group check. If automated equipment is used the group check should be performed by reloading and rescanning the Specimen. The ABO group of all donor red cell units and the Rh(D) group of those labelled as Rh(D) negative must be confirmed by the Laboratory undertaking the pretransfusion testing. C3.4(i) Blood group confirmation of donor red cell units must be performed by a forward group check. C3.4(ii) In the case of a branch Laboratory accepting units for pretransfusion testing from the parent Laboratory and the latter has checked the group of the units and the Laboratories are on the same IT and blood bank inventory systems, then the branch Laboratory can proceed directly to the pretransfusion testing. Confirmatory weak D testing of donor red cell units is not required. S3.5 Pretransfusion testing must include an antibody screen capable of detecting potentially clinically significant red cell antibodies. C3.5 Clinically significant antibodies are generally considered to be those, which are reactive by the indirect antiglobulin test (IAT) performed at 37°C. Note that anti-A, -B and -A, B must always be regarded as clinically significant. If the patient is known to have a red cell antibody, testing to exclude formation of additional antibodies must be undertaken for each new Specimen received if it is to be used for further crossmatching (see Appendix A). S3.6 The reagent red cells used for antibody screening must come from at least two separate group O donors and between them express the following antigens: C, c, D, E, e, M, N, S, s, K, k, Fya, Fyb, Jka, Jkb and Lea. The cells from different donors must not be pooled to achieve the desired range of antigen expression. One cell must be of R1R1 and another of R2R2 phenotype. The following phenotypes must be represented in the screening cells: Jk(a+b-), Jk(a-b+), Fy(a+b-) and Fy(a-b+). C3.6(i) Anti-Kpa and anti-Cw are rarely of clinical significance; consequently Kpa + and Cw+ screening cells are not essential. C3.6(ii) It is also desirable to include SS and ss phenotypes in the screening cells. S3.7 Antibody identification must be performed using a reagent red cell panel employing at least the method(s) by which the antibody is detectable. S3.8 The specificity of antibodies detected during antibody screening must be investigated and clinical significance assessed (see Appendix A). C3.8 S3.9 Antibody identification must be confirmed by typing patient’s cells for corresponding antigen(s) (if not transfused in the past 3 months), if antisera are available. Antibody identification may be referred to a reference Laboratory. The Laboratory must have procedures in place to exclude incompatibility between the recipient and donor. C3.9 It is essential that ABO incompatibility is excluded by whatever procedure is used. Group specific red cells must not be released solely on the basis of historical records. Only group O red cells are to be released in an emergency situation where there is no current group and screen. S3.10 If a computer crossmatching and remote release facility is used the following conditions must be met: (a) a comprehensive, validated, electronic data management system is in place (b) a valid pretransfusion Specimen has been tested in accordance with the requirements of S3.1 and S3.5 (c) there are no clinically significant antibodies detectable in the current Specimen and there is no history of clinically significant antibodies. S3.11 For a patient who has been transfused in the previous 3 months, Specimens must not be used more than 72 hours after collection. C3.11 The appropriate storage time for Specimens collected from immunocompromised or pregnant patients should be determined at the discretion of the Laboratory in conjunction with the attending clinician. S3.12 Specimen validity for pretransfusion testing is predicated by appropriate Specimen storage. C3.12 The following table outlines the requirements for Specimen storage in relation to transfusion and pregnancy status. Criteria The patient, in the last three months has been transfused Patients known not to have been transfused in the previous three months (refer to S3.11) Specimen collected in advance of elective surgery (‘preadmission’ Specimens) and where the patient’s history clearly excludes transfusion or pregnancy in the previous three months Specimen Validity 72 hours Storage conditions 7 days 2–6 C 1 month Serum/plasma must be separated and stored frozen at or below –20°C 2–6 C The above are working limits for Specimen storage if used for serological testing. 4. Antenatal and perinatal testing (Refer to Standard 6 in Requirements for Medical Pathology Services) S4.1 Request form and Specimen labelling for antenatal and perinatal testing must conform with the requirements in Section 1. S4.2 When performing blood grouping on antenatal patients, any discrepancy with historical records must be resolved. S4.3 Antibody screening and identification of detected antibodies must be performed consistent with the requirements in S3.5, S3.6 and S3.7. S4.4 The requirements for pretransfusion testing during pregnancy must be in accordance with Section 3. 5. Selection of blood components (Refer to Standard 6B in Requirements for Medical Pathology Services) Selection of red cells for transfusion S5.1 There must be clearly written policies on the selection of red cells for both routine and exceptional transfusion situations. C5.1 S5.2 Red cells that are negative for the relevant antigen where a clinically significant antibody is present or there is historical evidence of a clinically significant antibody, must be selected if available and time and clinical circumstances permit. Group O red cells must be selected when the patient's ABO group cannot be determined. C5.2(i) If a confirmed Rh(D) group cannot be obtained, Rh(D) negative red cells should be used until a definitive result is available. C5.2(ii) Red cell components should be of the same ABO and Rh(D) type as the patient whenever possible. Use of Rh(D) positive red cells in postmenopausal women and males who are Rh(D) negative may need to be considered in times of shortage. C5.2(iii) When transfusion is unavoidable and serologically compatible units are not available, taking into consideration the specificity of the antibody, incompatible units may be given after consultation between the responsible medical officer and a senior specialist from the transfusion Laboratory. C5.2(iv) Patients undergoing long-term transfusion regimens should have an extended phenotype performed (for example Cc, Ee, Jka, Jkb, Fya, Fyb, M, K, Ss – refer to S3.5) before their initial transfusion. Consideration should be given to providing red cells of the patient’s Rh and K types where readily available. Selection of non-red cell blood components Fresh frozen plasma, extended life plasma and cryoprecipitate S5.3 Plasma components of different blood groups must not be pooled. C5.3(i) Plasma components of any Rh(D) type may be given without regard to the recipient’s Rh(D) status. Anti-D immunoglobulin is not required if Rh(D) negative recipients receive plasma components from Rh(D) positive donors. C5.3(ii) Plasma components should be ABO-compatible with the recipient. However, at times of short supply of AB plasma group A plasma may be used for AB recipients. Platelet concentrates S5.4 Individual units of different ABO blood groups must not be pooled. C5.4(i) Platelet concentrates should be of the same ABO group as the recipient. Where crossing ABO groups is necessary consideration should be given to the type of platelet component, whether obtained by apheresis (currently suspended in plasma) or pooled (in platelet additive solution). C5.4(ii) It is important to ensure, where possible, that platelets from Rh(D) positive donors are not given to Rh(D) negative females of child bearing potential. If this occurs then administration of Rh(D) immunoglobulin at the recommended dosage may be considered to limit the risk of sensitisation. 6. Transfusion in special circumstances (Refer to Standard 6 in Requirements for Medical Pathology Services) Emergency transfusion S6.1 Specimens must be labelled in accordance with routine pretransfusion practice and standard pretransfusion testing performed (see Section 1 and Section 3). S6.2 Red cells must not be issued in emergency situations on the basis of an historical blood group alone. C6.2(i) If there is insufficient time to complete full pretransfusion testing, ABO and Rh(D) compatible red cells (preferably group specific) may be issued once the patient’s ABO and Rh(D) blood group has been determined (see S3.1). C6.2(ii) Plasma components should be ABO-compatible with the recipient. However, at times of short supply of AB plasma group A plasma may be used for AB recipients. Where blood components are required before pretransfusion testing can be performed: (a) red cells must be group O (b) plasma components must be group AB. S6.3 If the antibody screen is positive or a subsequent crossmatch incompatible, the treating clinician must be informed. S6.4 The Laboratory must have criteria for the issue of Rh(D) positive red cells and platelets when Rh(D) negative stocks of these components are limited. S6.5 Red cells issued before completion of pretransfusion testing must be clearly labelled for example ‘Uncrossmatched blood’ or ‘Emergency issue compatibility testing not completed’. C6.5 Rh(D) positive red cells and platelets should not be given to Rh(D) negative females with child bearing potential, except in life threatening circumstances. If this occurs then administration of anti-D immunoglobulin may be considered to limit the risk of sensitisation. Massive blood loss / critical bleeding S6.6 The Laboratory must have a written policy for provision of blood components and blood products in massive blood loss / critical bleeding. Antenatal and neonatal settings Guidance on the selection and use of blood components and blood products in antenatal and neonatal settings should be sought from current ANZSBT documentation1. Transfusion of patients with Autoimmune Haemolytic Anaemia S6.7 The Laboratory must have a written procedure for the serological investigation of patients prior to provision of red cell components, if clinically necessary, for patients found to have autoantibodies due to autoimmune haemolytic anaemia (AIHA). Prior to the provision of red cells, consultation with the treating clinician must occur. Recipients of haemopoietic progenitor cells S6.8 Laboratories involved in the provision of blood components to recipients of haemopoietic stem cell grafts must have clear protocols on the selection of blood components with respect to ABO and Rh(D) groups of recipient and donor. C6.8 7. Guidance relating to the use of blood components in this setting should be sought from the NPAAC document Requirements for Procedures Related to the Collection, Processing, Storage and Issue of Human Haemopoietic Progenitor Cells and from ANZSBT documentation1. Autologous transfusion (Refer to Standard 6A in Requirements for Medical Pathology Services) S7.1 All Laboratories involved in the provision of a pre-donation autologous blood service must have clear protocols for the collection, testing, storage and issue of these units, as appropriate to the service provided. S7.2 All autologous units must be clearly labelled to distinguish them from allogeneic (homologous) units (and stored in a separate designated area). Screened and unscreened autologous units must be separated and stored in designated areas. S7.3 Pretransfusion testing, labelling and documentation must be performed in accordance with S1, S3 and S5. 8. Transfusion reactions (Refer to Standard 6 in Requirements for Medical Pathology Services) S8.1 The Laboratory must have systems in place to identify or be notified of reactions or other adverse events associated with transfusion. S8.2 The Laboratory must have written procedures for the recording, management, investigation and reporting of suspected transfusion reactions or other transfusion-related adverse events to the relevant provider of the blood component or blood product. S8.3 Suspected transfusion transmission of bacterial or viral infections must be immediately reported to the relevant manufacturer of the component or product. 9. Storage and transport of blood components and blood products (Refer to Standard 3 and Standard 5 in Requirements for Medical Pathology Services) S9.1 There must be policies dealing with storage and transport of blood components and blood products. C9.1(i) Blood components and blood products must be stored in an appropriate temperature controlled (and monitored) environment to conform with AS 3864 Medical Refrigeration Equipment — For the Storage of Blood and Blood Components3. 10. C9.1(ii) Other blood components and blood products must be stored according to the Australian Red Cross Blood Service document Blood Component Information (Circular of Information) 20124. C9.1(iii) Blood components and blood products must be transported in a manner suitable for purpose to maintain specified transport temperatures. Where containers are used for transport purposes, these must be validated. C9.1(iv) For each storage facility there must be written procedures for handling blood components and blood products stored outside temperature specifications Quality Assurance and Quality Control (Refer to Standard 7 in Requirements for Medical Pathology Services) Appendix A (Normative) Selection of red cells where antibodies are reactive by indirect antiglobulin test (IAT) at 37°C Specificity Clinically significant Selection of unitsa Anti-A1 Rarely IAT crossmatch compatible Anti-HI (in A1 and A1B patients) Rarely IAT crossmatch compatible Anti-D, -C, -c, -E, -e Yes Antigen negative Anti-CW Rarely IAT crossmatch compatible Anti-K, -k Yes Antigen negative Anti-Kpa Rarely IAT crossmatch compatible Anti- Jka, -Jkb Yes Antigen negative Anti-M Sometimes IAT crossmatch compatible Anti-N Sometimes IAT crossmatch compatible Anti-S, -s, -U Yes Antigen negative Anti-Fya, -Fyb Yes Antigen negative Anti-P1 Rarely IAT crossmatch compatible Anti-Lea, -Leb, -Lea+b Rarely IAT crossmatch compatible Anti-Lua Rarely IAT crossmatch compatible Anti-Wra Rarely IAT crossmatch compatible High titre low-avidity antibodies (HTLA) Unlikely Antibodies against low or high frequency antigens Depends on specificity Local Laboratory policy or seek advice from reference Laboratory Local Laboratory policy or seek advice from reference Laboratory Other antibodies active by IAT at 37°C Seek advice from reference Laboratory a Where antigen negative red cells are specified these should also be IAT crossmatch compatible (at 37°C)] References 1.
