Epic Test Code LAB21005 Lipase: Body Fluid
Performing Location(s)
BMC
Specimen Type
Body Fluid
Preferred Container
Red top tube
Alternate Container
Green top tube
Minimum Volume to Submit for Testing
0.5 mL Body Fluid
- Multiple test can be performed from this volume. For question please contact the lab at 547-3975.
Storage Requirements
Sample tubes should be centrifuged within 2 hours of collection, if bloody, followed by transfer to a labeled plastic, aliquot tube. If not bloody, send primary collection tube to lab.
Lipase is stable at room temperature for one week and three weeks at refrigerator temperature (2-8° C)
Transportation Needs
Deliver specimen to the laboratory within 1 hour of collection.
Causes for Rejection
Mislabeled or unlabeled specimen
Specimen grossly hemolyzed
Limitations
Bacterial contamination of the specimen may cause increased lipase values
Hemoglobin at a test concentration of 500 mg/dL [0.31 mmol/L] increases the lipase activity by 30 U/L at a lipase level of 143 U/L. Hemoglobin at a test concentration of 500 mg/dL [0.31 mmol/L] has less than 10% interference at lipase levels greater than 300 U/L.
EDTA, potassium oxalate, sodium fluoride and citrate have been shown to inhibit lipase results and should not be used.
Reference Range for body fluid is not established.

Additional Information
Contraindications:
Lipase is increased in approximately 50% of patients with chronic renal failure. Serum lipase increases with hemodialysis. Therefore, predialysis blood samples are recommended for lipase movement.
