ALT (SGPT) Liquid Reagent (A524‐780TM)
Number of Tests:
Normal Range: Male: 10‐40 U/L(37°C)
Female: 7‐35 U/L(37°C)
It is strongly suggested that each laboratory establish its own range of expected values.
Discard if either reagent appears to be cloudy or contains particulate matter.
The working reagent is stable for 2 weeks at 2‐8°C. The working reagent should be
discarded if the initial absorbance, read against distilled water at 340nm, is below 1.000.
Limitations of Procedure:
Hemolysis must be avoided as the concentration of ALT in red cells is roughly 5 times
that of serum.
