Methodology
Immunoassay (IA) • Immunotyping • Immunofixation
Assay category
This test was developed and its analytical performance characteristics have been determined by Quest Diagnostics. It has not been cleared or approved by the U.S. Food and Drug Administration. This assay has been validated pursuant to the CLIA regulations and is used for clinical purposes.
Specimen requirements | |
|---|---|
| Patient preparation | Overnight fasting is required |
| Preferred specimen(s) | 18.9 mL serum collected in a red-top tube (no gel) |
| Minimum volume | 9.5 mL |
| Collection instructions | See individual tests. Multiple tubes required for testing. Cryoglobulin Screen and reflex: 3 mL serum required: 2 mL minimum. Since multiple tubes are needed for this panel, designate one tube exclusively for cryoglobulin and treat it differently from the other tubes collected. Allow blood in the tube designated for cryoglobulin to clot for one (1) hour in a 37° C 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 cryoglobulin serum into one transport 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° C during clotting, the cryoglobulin, if present, can precipitate during centrifugation and be lost in the clot resulting in a false negative result. |
| Transport container | Transport tubes |
| Transport temperature | See individual tests |
| Specimen stability | See individual tests |
| Reject criteria | Gross hemolysis • Grossly lipemic • Received room temperature • Icteric specimens • Serum separator tube (SST) for Cryoglobulin • Plasma • Microbial contamination may interfere |
