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. Refrigerate the specimen if unable to assay within 8 hours of collection. It is recommended that the serum or plasma be separated from contact with cells within 2 hours from time of
collection. 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.)

Limitations

Venipuncture immediately after or during the administration of Metamizole (Dipyrone) may lead to
falsely low results for HDL. Venipuncture should be performed prior to the administration of Metamizole.
