Preferred Specimen
LABCORP LAB: GREY TOP (Refrigerated) Min Vol: .5


Instructions
Draw 3 mL blood into chilled gray-top tube


Transport Temperature
Specimen Perchloric acid supernatant from oxalated whole blood Volume 0.5 mL (clear supernatant) Minimum Volume 0.2 mL (clear supernatant) Container Gray-top (sodium fluoride) tube Patient Preparation: Patient should be in a fasting and resting state (should not exercise). Collection Draw blood into chilled gray-top tube. Immediately after blood is drawn, add 2 mL of whole blood from the gray-top tube to 2 mL of 8% perchloric acid (7 mL of 70% perchloric acid diluted to 100 mL with deionized water). Note: Use 1:1 blood (ie, equal parts) to 8% perchloric ratio if less blood is obtained. Shake mixture vigorously for about 30 seconds. Refrigerate for five minutes to ensure complete protein precipitation. Centrifuge 5 to 10 minutes at approximately 1500xg. Immediately transfer the clear supernatant to a transport tube. Label the transport tube as ""supernatant"" and send to the laboratory. Note: A second centrifugation of the supernatant may be necessary to obtain a clear protein-free solution. Storage Instructions Maintain the perchloric acid supernatant refrigerated Stability: Room temperature: 5 days Refrigerated: 7 days Frozen: 7 days
