Processing Instructions: Allow blood to clot for one (1) hour in a 37 degrees Celsius water bath, incubator, heat block, or heel warmer. After clotting, centrifuge the specimen as quickly as possible. It is not necessary to use a warm centrifuge but do not use a Refrigerated one. Decant all of the serum into one screw-cap vial (do not aliquot any of the cryoglobulin serum into any other tube). Transport at room temperature. NOTE: If the sample is NOT kept at 37 degrees Celsius during clotting, the cryoglobulin, if present, can precipitate during centrifugation and be lost in the clot resulting in a false negative result.NOTE: No tests can be added or poured off of tubes; cryocrit and cryoglobulin evaluation only.Preferred Testing Volume: 3.0 mL SerumMinimum Testing Volume: 2.0 mL Serum Transport Temperature: Ambient Stability: Ambient: 14 daysRefrigerated : 14 daysFrozen: 30 days Causes for Rejection: Gross hemolysisGross lipemiaGross icterusReceived Refrigerated Received frozenCollected in SSTPerforming Lab: Quest Diagnostics Chantilly
