Special Info

Decant plasma/serum from cells within 2 hours of collection. Indicate patient fasting hours when the specimen was collected. Fasting is not required, but the information is helpful for test interpretation. Carnitine, fish oil and omega-3 supplements affect test results; indicate supplement use on the requisition.
