Label Mnemonic:	TPO
Epic code:	LAB844
Downtime form:	Doctor/Provider Orders - Pathology Core and Specialty Care Nursery

Chemistry
6240 RCP
356-3527

Specimen(s):

Body Fluid
(e.g., surgical drain, pericardial, peritoneal, peritoneal dialysis, pleural, or synovial)

Collection Medium:

Red top tube 5 mL (Clot Activator)

Minimum:

1 mL fluid in red top tube

Rejection Criteria:

Plasma, serum, urine, or cerebrospinal fluid.

Testing Schedule:

24 hrs/day, 7 days a week, including holidays.

Turn Around Time:

1 hour (upon receipt in laboratory)

Reference Range:

No established reference range (see Test Limitations)

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 total protein in cerebrospinal fluid, pericardial fluid, peritoneal/ascites fluid, pleural fluid, and synovial fluid shows no evidence of systematic matrix interference. Results should be interpreted in conjunction with clinical findings.
