Specimen Requirement

0.5 mL serum or plasma is required.

Additional Specimen Collection Information

Collect blood in a lithium heparin, green-top or red-top tube from a fasting patient. (A 12 hour fast is recommended.) PST and SST (gel tubes) are acceptable. Serum or plasma should be separated from contact with cell within 2 hours of collection. Refrigerate the specimen if unable to assay within 8 hours of collection. Hemolyzed specimens are not acceptable.Lipemic specimens must be cleared prior to analysis.

Performance

Testing is performed Monday through Sunday.

Routine orders: Typically completed within 4 hours after the specimen arrives at the testing site.

Expedite orders: Typically completed within 1 hour after the specimen arrives at the testing site.

STAT orders: Typically completed within 30 minutes after the specimen arrives at the testing site.
