Test Code 786 Lipid Cascade (Reflexes to LDL, Direct)

Important Note

When the Triglyceride results are >400 mg/dL authorization has been obtained to reflex to order, run and report an LDL, Direct.

Current lipid guidelines are based on fasting samples. While there are likely only minor changes between fasting and non-fasting parameters, cardiovascular risk assessment using non-fasting samples are not yet well established.

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. PST and SST (gel tubes) are acceptable. 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.)

Performance

Testing is performed Monday through Sunday.

Typically completed the same day order is received.
