and each unit of blood or component
o The intended recipient’s two independent
identifiers, ABO group and Rh type.
o The donor identification number, ABO group and

Reissuing Blood and Components

Conditions for reissuing blood and components that have
been returned to the lab
o Container closure has not been disturbed
o All components maintained at the appropriate
temperature
o At least one sealed segment of integral donor tubing
has remained attached to the container. Removed
segments shall be reattached only after confirming
that the tubing identification numbers on both the
removed and the container are identical.
o The records indicate that the blood or component has
been inspected and that it is acceptable for reissue
Urgent Requirement for Blood Components

RBCs ABO group to be transfused to the patient
o Recipients whose ABO group is not known shall
receive O RBCs
o If blood is issued before completion of compatibility
testing, ABO type of RBCs or whole blood Should be
compatible with the recipient’s ABO group that has
been determined
 The container tie tag or label: should indicate clearly
that compatibility and/or infectious disease testing was
not completed at the time of issue
 Compatibility testing:
should be completed quickly using a patient sample
collected as early as possible

Records:
should contain a signed statement from the requesting
physician indicating that the clinical situation was
sufficiently urgent to require release blood before
completion of compatibility testing or infectious disease
testing
 The transfusion service medical director and the
recipient’s physician should be notified immediately of
abnormal test results that may affect patient safety.

 Identification of a Transfusion Reaction
 Clinical Evaluation and Management of Transfusion
Reactions (Patient and Component-focused steps)
 Standard Laboratory Investigations of Transfusion
Reactions
1. Clerical check of the component bag, label, paperwork,
and patient sample.
2. Repeat ABO testing on the posttransfusion sample.
3. Visual check of pre- and posttransfusion sample to look
for evidence of hemolysis (hemolysis may not be visible
if <50 mg/dL of hemoglobin is present).
4. Posttransfusion sample direct antiglobulin test (DAT).
(If positive, DAT should also be performed on a
pretransfusion specimen)
5. Findings reported to blood bank supervisor or medical
director, who may request additional studies or tests.
 Additional laboratory evaluation may be required
when an HTR is suspected:
1. Human error must be ruled out, primarily in the area of
patient and sample identification. Repeat ABO and Rh
testing should be performed on the unit of blood or
available segment, pretransfusion specimen, and posttransfusion sample to exclude any clerical errors or
sample mix-ups.
2. Antibody detection studies should be performed on the
pre- and posttransfusion samples to look for any
previously undetected alloantibodies.

3. The crossmatch should be repeated with both pre- and
posttransfusion specimens using the indirect antiglobulin
test (IAT) method, which has increased sensitivity over
the immediate spin crossmatch.
4. When laboratory evidence of hemolysis is not evident,
demonstration of decreased red cell survival may aid in
the diagnosis. Serial hemoglobin levels may be adequate,
or red cell survival studies may be required in more
complex cases. Phenotypic differences be- tween the
donor and the patient can be identified and followed
using flow cytometry. The patient may be evaluated by
serial mea- surement of certain laboratory values such as
haptoglobin, lactate dehydrogenase (LDH), and
unconjugated bilirubin levels. An increase in bilirubin
may begin as early as 1 hour after the reaction, peak at 5
to 7 hours, and disappear within 24 hours if liver function
is normal.
5. Examination of the returned components may yield
important information concerning possible traumatic or
mechanical causes of hemolysis. Both the blood bag and
the administration tubing should be included in the
examination. Hemolysis in both the component container
and administration set could result from a process that
affected the unit of blood, such as inappropriate warming
of the unit. If the hemolysis was present only in the
administration set, a faulty infusion pump, if used, could
be the cause. The transfusion service must retain any
patient records that are related to transfusion reactions,
clinically significant antibodies, and special transfusion
requirements. Additional information regarding special
products, such as irradiated or washed components
required for a particular patient, may be retained by the
transfusion service as well.
 Specialized Laboratory Investigations for Selected
Reactions:

Anaphylaxis: the patient should be tested for antibodies
to immuno- globulin A (anti-IgA). IgA-deficient patients
should be transfused with components from IgAdeficient donors. Washed cellular blood components may
be considered in these patients.

Sepsis: Visual examination of the returned compo- nent
should be conducted in suspected cases of
posttransfusion sepsis, paying particular attention to any
color changes, especially brown or purple discoloration
in a red cell component, and bubbles, especially
frothiness in a platelet component. A Gram’s stain should
be performed on the returned compo- nent, and cultures

should be performed on both the component and the
patient’s post- transfusion blood sample.
Transfusion-Related Acute Lung Injury: In cases of
suspected transfusion-related acute lung injury (TRALI),
the collecting facility should be consulted to coordinate
the ap- proach to posttransfusion testing. Patient samples
should be obtained at the time of the reaction because
they may not be available at a later date. A serum sample
should be drawn for antibody studies, and an acid-citratedex- trose tube should be drawn for HLA typing. The
collecting facility may obtain a sample of the donor’s
serum to test for HLA and neutro- phil antibodies.
