      Product Description


      •  AutoPure AST GOT is a reagent kit for direct quantitative determination of aspartate transaminase AST in human serum and plasma on automated
      • clinical chemistry analyzers
      •  AutoPure AST GOT is a ready to use two liquid reagent system
      • With AutoPure AST GOT the assay is linear upto 800 IUI 1336 ukatI
      • Ketoglutarate reacts with L aspartate in the presence of AST GOT to form oxaloacetate and L glutamate
      • Ketoglutarate  Laspartate oxaloacetate  L glutamate
      • The increase in oxaloacetate is determined in an indicator reaction catalyzed by malate dehydrogenas oxaloacetate  NADH  H Lmalate  NAD
      • The conversion of NADH to NAD  is proportional to the AST GOT activity in the specimen and is determined kinetically 

      Reagent Storage Stability  Handling

      AutoPure AST GOT is a ready to use two liquid reagent system

      Shelf  Life 

      Stable till the expiry date indicated on the label when stored at 20  80C

      On - Board Reagent Stability

      • R1  30 days at 20 - 80 C after opening. Protect the reagent from light andcontamination.
      • R2  30 days at 20 - 80 C after opening. Protect the reagent from light and contamination.

      Do not freeze the reagent 

      Specimen Collection & Preservation

      Collect sample using standard sampling tube. Although serum is preferred, heparinized plasma or EDTA  plasma can also be used. Specimen with any visible haemolysis is not acceptable, since erythrocytes contain approximately ten times the normal concentration of AST (GOT) found in serum. AST (GOT) in serum  plasma is stable for 7 days at 20  - 80C and for 30 days at -100C. Centrifuge samples containing precipitate before performing assay


      • Fully automated systems automatically calculate the AST (GOT) activity of each sample.
      • Results in ukat/l = Results in IU/I x 0.0167

      Application Sheets

      Application sheets for the popular fully automated analyzers are provided along with the kit. For additional system applications, contact our local Accurex representative.


      Determine the factor using a calibrator. For calibration, it is recommended to use C.f.a.s.or any other suitable calibrator material 

      Calibration frequency :

      Re calibration is recommended

      •  Whenever the reagent lot is changed
      •  As per the requirements of quality control procedures 
      Quality Control

      Each batch of AutoPure AST (GOT) is assayed with at least six quality control sera  Precinorm, Precipath  Biorad l  Biorad II, Sero Low and Sero High prior to release

      To ensure adequate quality control, it is recommended that the laboratory should use a normal and an abnormal commercial reference control serum. It should be realized that the use of quality control material checks both reagent and instrument functions together. The value of these controls should fall within the specified limits. If control values fall outside specified limits, each of the below criteria should be cross-checked and corrected :

      •  Proper instrument function  wavelength setting, light source and temperature control
      • Cleanliness of probes & cuvettes
      •  Bacterial contamination of wash water used by the instrument
      •  Expiry date of the reagent kit.

      • From 370 C to 250 C : 0.49 

       Note :

      Expected range varies from population to population. It is therefore recommended that each laboratory should establish its own normal range. For diagnostic purposes, the AST (GOT) results should always be assessed in conjunction with the patient s medical history, clinical examinations and other findings.

      Performance Characteristics


      With AutoPure AST (GOT), the assay is linear upto 800 IU/I (13.36 ukat/l). Determine samples with higher concentrations via the rerun function. On instruments without rerun function, manually dilute samples with higher concentrations using 0.9  NaCl or distilled / deionized water (e.g. 1 + 2). Multiply the result by the appropriate dilution factor (e.g. 3).


      There is no significant interference in samples containing upto 60 mg/dl of bilirubin. Haemolysis interferes due to AST activity from erythrocytes.
