(e.g., surgical drain, pericardial, peritoneal, peritoneal dialysis,
pleural, or synovial)
|Red top tube 5 mL (Clot Activator)
1 mL fluid in red top tube
Plasma, serum, urine, or cerebrospinal fluid.
24 hrs/day, 7 days a week, including holidays.
1 hour (upon receipt in laboratory)
No established reference range (see Test Limitations)
This test is not approved by the FDA for this sample type. Performance
characteristics and reference range have not been verified. A
published study using Roche Diagnostics cobas 8000 analyzers has
demonstrated that analysis of amylase in drain fluids, pancreatic
fluid, peritoneal/ascites fluid, and pleural fluid shows no evidence
of systematic matrix interference. Results should be interpreted in
conjunction with clinical findings.
