Standard Volume: 2 mL serum.
Minimum Volume: 0.8 mL serum.
Transport: Refrigerated or frozen on dry ice.
Rejection Criteria: Gross lipemia or gross hemolysis; icteric specimen; heat inactivation; bacterial contamination; specimen frozen and thawed more than once; refrigerated specimen received in laboratory more than 24 hours after collection.
