87080:ALKALINE PHOSPHATASE ISOENZYMES
Alias Names: Phosphatase Isoenzymes
Methodology: Heat Inactivation / Enzymatic
Edit Date: 6/11/2010
Performed: Daily
Released: 24-72 hours after setup at PeaceHealth Laboratories’ reference lab.
CPT Code: 84080-90
Specimen Collection Details
Collection: One 7.5 mL serum separator tube (SST). Also acceptable: One 4 mL green top tube (heparin). Fasting specimen is recommended.
Handling: Allot to clot, centrifuge and separate serum from cells immediately and pour into a plastic vial. Freeze. Allow no more that one freeze/thaw cycle.
Stability: After separation specimen stable 1 hour ambient, 7 days refrigerated (total activity will increase 2% per day), or 1 year frozen. Allow no more than one freeze/thaw cycle.
Standard Volume: 2 mL serum or plasma.
Minimum Volume: 1 mL serum or plasma.
Transport: Frozen on dry ice.
Comments: This test cannot be added on at a later date due to stability.

Heat-stable isoenzymes, such as the one produced during pregnancy, will interfere with the interpretation of this assay.

Rejection Criteria: EDTA, sodium fluoride/potassium oxalate plasma, or hemolyzed specimen.
