AST(SGOT) Liquid Reagent (A559‐150)
Number of Tests:
500 U/L at 37°C
8‐33 U/L at 37°C
It is strongly suggested that each laboratory establish its own range of expected values.
Discard the reagents if either appears cloudy or contains particulate matter. The working
reagent should be discarded if the initial absorbance, read against distilled water at 340
nm, is below 1.100.
Limitations of Procedure:
Hemolysis must be avoided as the concentration of AST in red cells is roughly 10 times
that of serum.
Grossly icteric or turbid specimen may require the use of a sample blank.
AST values for neonatal patients have not been established with this procedure.
