0.5 mL serum or plasma is required.
Additional Specimen Collection Information
Collect blood in a lithium heparin, green-top or red-top tube. A 12 hour fast prior to collection is preferred but not required.

Specimens not centrifuged within 4 hours of collection may be rejected. If the patient is unable to be redrawn, the test may be performed at the request of the ordering clinician and results will carry a disclaimer. (Disclaimer: the specimen was not received in the recommended fashion (delayed cell separation from serum or plasma. Results should be interpreted with caution.)
