Performed by Parnassus & Mission Bay Chemistry
In House Availability Test available 24 hours per day 7 days per week
Method Spectrophotometric (see Additional Information)
Container type Light green top preferred, Gold top acceptable
Amount to Collect 1 mL blood
Sample type Plasma or serum
Preferred volume 0.5 mL plasma or serum
Min. Volume 0.2 mL plasma or serum
Units U/L

Normal range was determined by testing 271 male and female healthy adult blood donors at UCSF.
Stability Room temperature 8 hours, refrigerated 2 days, frozen at -20C 1 week
Turn around times 4 hours
Additional information Method: Kinetic assay with spectrophotometric detection of methylresorufin from the substrate 1,2-0-dilauryl-rac-glycero-3-glutaric acid (6'-methylresorufin)-ester. Colipase is used to stabilize the lipase and deoxycholate to reduce the activity of non-pancreatic lipases.

Lipase can at times be elevated in pancreatitis when amylase is normal, but may also be falsely elevated in a variety of non-pancreatic disorders (e.g., GI disease, renal insufficiency). This test is not ordinarily offered stat except for potential pancreas transplant donor samples.
