10 x 6 mL bottles
6 hours at 15‐30°C
3 days at 2‐8°C
8,000 IU/L at 30°C

The reagent should be discarded if: (1) moisture has penetrated the vial and caking has
occurred; (2) The reconstituted reagent has as absorbance against water greater than
1.200 at 405 nm.
Limitations of Procedure:
Hemolyzed serum samples should not be used. Certain drugs and other substances are
also known to affect cholinesterase activity.
Extremely lipemic samples or icteric serum should have blank correction performed.
