Lipase, Plasma / Serum
|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|
|Normal range||19-56 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.
