Remove the reagent caps from two bottles of . 2. Prepare the Working Reagent by adding 10 mL of sterile water to each of the two bottles. The Lactic Acid assay is used for the quantitation of lactic acid in human plasma. SUMMARY AND EXPLANATION OF TEST Lactic acid, an intermediary in carbohydrate metabolism, is derived predominantly from skeletal muscle, brain, and erythrocytes. The blood lactate concentration is dependent on the rate of production and the rate of metabolism in the liver and kidneys. Approximately 30% of total lactate production is used by the liver. Moderate increase in lactate production results in increased hepatic lactate clearance, but uptake by the liver is saturable when concentrations exceed 2 mmol/L. For example, during strenuous exercise, lactate concentrations may increase significantly, from an average concentration of about 0.9 mmol/L to more than 20 mmol/L within 10 seconds.1 The review by Stacpoole2 describes the biochemistry and pathobiology of lactate metabolism. A pivotal characteristic of this metabolism is that lactate can only arise from reduction of pyruvate. Elevated lactate associated with reduced arterial pH is called lactic acidosis. Tissue hypoxia is the most common cause of lactic acidosis and is classified as Type A, while lactic acidosis that is nonhypoxic is classified as Type B. Under normal conditions, the concentration of lactate is about 10-fold higher than that of pyruvate. Shock is perhaps the most widely recognized cause of lactic acidosis; however, in some cases, excess lactate production may precede shock. Such conditions as myocardial infarction, severe congestive heart failure, pulmonary edema, and blood loss are common causes of shock associated with lactic acidosis. Other causes of lactic acidosis include intravenous infusion of substances such as fructose, sorbitol, or epinephrine, and large doses of drugs such as ethanol or acetaminophen. Hepatic necrosis, neoplasms, lymphomas, and various forms of leukemia have been reported to cause lactic acidosis. In diabetic coma, lactic acidosis is common.3 10 mL H2 O + R1 = Working Reagent 1 1. 2. 3. 4. For in vitro diagnostic use. Do not use components beyond the expiration date.

Reagent Kit 9D89 Lactic Acid is supplied as a lyophilized, single reagent kit which contains: 10 x 10 mL Funnels (5) Bar code labeled cartridges (5) SPECIMEN COLLECTION AND HANDLING Suitable Specimens Plasma is the acceptable specimen. Plasma: Use plasma collected by standard venipuncture techniques into glass or plastic tubes without gel barriers. The acceptable anticoagulant is sodium fluoride/potassium oxalate. Venous specimens should be obtained without the use of a tourniquet or immediately after the tourniquet has been applied. If there is any delay in obtaining the specimen, the tourniquet should be removed after the puncture has been performed, and the blood should be allowed to circulate for at least two minutes before sample is withdrawn. Patients should avoid exercise of the hand or arm immediately before and during the procedure. Centrifuge the specimen as soon after collection as possible and immediately remove the plasma from the red blood cells.1 Ensure centrifugation is adequate to remove platelets. For total sample volume requirements, refer to the instrument-specific ASSAY PARAMETERS section of this package insert and Section 5 of the instrument-specific operations manual. Estimated tests per kit: 393 Calculation is based on the minimum reagent fill volume per kit. Chromogen precursors = Precautions for Users REAGENTS Peroxidase (Horseradish) R1 WARNINGS AND PRECAUTIONS Lactic acid is converted to pyruvate and hydrogen peroxide (H2O2) by lactate oxidase. Peroxidase catalyzes the oxidation of chromogen precursor by H2O2 to produce a colored dye. The increase in absorbance at 548 nm is directly proportional to the lactic acid concentration in the sample. Methodology: Lactic Acid to Pyruvate Lactate Oxidase + 3.

Place the cartridge in Reagent Supply Center 1. PRINCIPLES OF PROCEDURE Reactive Ingredients 10 mL H2 O Concentration 400 U/L 2,400 U/L As required Inactive Ingredients: Contains buffer, fillers, and stabilizers. REAGENT HANDLING AND STORAGE Reagent Handling Remove air bubbles, if present in the reagent cartridge, with a new applicator stick. Alternatively, allow the reagent to sit at the appropriate storage temperature to allow the bubbles to dissipate. To minimize volume depletion, do not use a transfer pipette to remove the bubbles. CAUTION: Reagent bubbles may interfere with proper detection of reagent level in the cartridge, causing insufficient reagent aspiration which could impact results. Specimen Storage Plasma: Separated plasma may be analyzed immediately, stored at 2 to 8°C, or frozen. Samples are stable for 14 days at 2 to 8°C or up to 4 weeks at -20°C. Specimen stability was verified in an in-house study of 20 sodium fluoride/potassium oxalate plasma samples. NOTE: Stored specimens must be inspected for particulates. If present, mix and centrifuge the specimen to remove particulates prior to testing. Reagent Storage Unopened reagents are stable until the expiration date when stored at 2 to 8°C. Do not pool reagents. Reagent stability is 7 days if the reagent is uncapped and onboard. 2 PROCEDURE RESULTS Materials Provided Refer to the instrument-specific operations manual for information on results calculations. • ARCHITECT System Operations Manual—Appendix C • AEROSET System Operations Manual—Appendix A Representative performance data are given in the EXPECTED VALUES and SPECIFIC PERFORMANCE CHARACTERISTICS sections of this package insert. Results obtained in individual laboratories may vary. 9D89 Lactic Acid Reagent Kit Materials Required but not Provided • 1E75 Lactic Acid Calibrator 1 x 10 mL • Control Material • Saline (0.85% to 0.90% NaCl) for specimens that require dilution Assay Procedure LIMITATIONS OF THE PROCEDURE For a detailed description of how to run an assay, refer to Section 5 of the instrument-specific operations manual. Refer to the SPECIMEN COLLECTION AND HANDLING and SPECIFIC PERFORMANCE CHARACTERISTICS sections of this package insert. The performance characteristics of Lactic Acid on an analyzer other than an ARCHITECT c Systems or the AEROSET System must be validated and verified. Specimen Dilution Procedures The ARCHITECT c Systems and the AEROSET System have automatic dilution features; refer to Section 2 of the instrument-specific operations manual for additional information. Plasma: Specimens with lactic acid values exceeding 120.0 mg/dL (13.32 mmol/L) are flagged and may be diluted using the Automated Dilution Protocol or the Manual Dilution Procedure. EXPECTED VALUES Reference Range Plasma8 Automated Dilution Protocol If using the Automated Dilution Protocol, the system performs a dilution of the specimen and automatically corrects the concentration by multiplying the result by the appropriate dilution factor. To set up the automatic dilution feature, refer to Section 2 of the instrument-specific operations manual for additional information. Venous Range (mg/dL) Range (mmol/L) 4.5 to 19.8 0.5 to 2.2 To convert results from mg/dL to mmol/L, multiply mg/dL by 0.111. A study was conducted using 204 plasma samples from 99 female and 105 male volunteers. Data were analyzed as described by Solberg9 and Clinical and Laboratory Standards Institute (CLSI) protocol NCCLS C28-A.10 From this study, 95% of male specimens fell within 5.0 to 19.4 mg/dL, with male samples ranging from 3.9 to 20.6 mg/dL. For female specimens, 95% fell within 4.7 to 16.8 mg/dL, with female samples ranging from 4.5 to 18.6 mg/dL. It is recommended that each laboratory determine its own reference range based upon its particular locale and population characteristics. Manual Dilution Procedure Manual dilutions should be performed as follows: • Use saline (0.85% to 0.90% NaCl) to dilute the sample. • The operator must enter the dilution factor in the patient or control order screen. The system uses this dilution factor to automatically correct the concentration by multiplying the result by the entered factor. • If the operator does not enter the dilution factor, the result must be multiplied by the appropriate dilution factor before reporting the result. NOTE: If a diluted sample result is flagged indicating it is less than the linear low limit, do not report the result. Rerun using an appropriate dilution. For detailed information on ordering dilutions, refer to Section 5 of the instrument-specific operations manual. SPECIFIC PERFORMANCE CHARACTERISTICS Linearity Lactic Acid is linear up to 120.0 mg/dL (13.32 mmol/L). Linearity was verified using CLSI protocol NCCLS EP6-A.11 Limit of Detection (LOD) The LOD for Lactic Acid is 0.05 mg/dL (0.006 mmol/L). The LOD is the mean concentration of an analyte-free sample + 2 SD, where SD = the pooled, within-run standard deviation of the analyte-free sample. CALIBRATION Calibration is stable for approximately 7 days (168 hours). Calibration is required whenever a new reagent is reconstituted. Verify calibration curve with at least two levels of controls according to the established quality control requirements for your laboratory. If control results fall outside acceptable ranges, recalibration may be necessary. For a detailed description of how to calibrate an assay, refer to Section 6 of the instrument-specific operations manual. For information on calibrator standardization, refer to the Lactic Acid Calibrator package insert. Limit of Quantitation (LOQ) The LOQ for Lactic Acid is 0.18 mg/dL (0.020 mmol/L). The LOQ is the analyte concentration at which the CV = 20%. Interfering Substances Interference studies were conducted on the AEROSET System using CLSI protocol NCCLS EP7-P.12 Interference effects were assessed by Dose Response and Paired Difference methods, at the medical decision level of the analyte. Interfering Substance QUALITY CONTROL The following process is the recommendation of Abbott Laboratories for quality control. As appropriate, refer to your laboratory standard operating procedure(s) and/or quality assurance plan for additional quality control requirements and potential corrective actions. • Two levels of controls (normal and abnormal) are to be run every 24 hours. • If more frequent control monitoring is required, follow the established quality control procedures for your laboratory. • If quality control results do not meet the acceptance criteria defined by your laboratory, patient values may be suspect. Follow the established quality control procedures for your laboratory. Recalibration may be necessary. • Review quality control results and acceptable criteria following a change of reagent or calibrator lot.
