Specimen Requirements
| Volume | Type | Container | Collect Temperature | Transport Temperature | Special Instructions |
|---|---|---|---|---|---|
| 3 mL | Serum | No additive (Red) | See note | Refrigerated | Collect in 2 pre-warmed 6 mL red top tubes and fill completely. Do not use serum separator tubes. Immediately after collection, place tubes in heel warmer or 37°C (warm, not hot) water. Keep samples warm, and allow to clot at 37°C for 90 minutes. Centrifuge at 37°C, if possible (do not use refrigerated centrifuge), and separate serum from cells. Refrigerate and transport serum after removal from cells. |

Special Info
Collect in 2 pre-warmed 6 mL red top tubes and fill completely. Do not use serum separator tubes. Immediately after collection, place tubes in heel warmer or 37°C (warm, not hot) water. Keep samples warm, and allow to clot at 37°C for 90 minutes. Centrifuge at 37°C, if possible (do not use refrigerated centrifuge), and separate serum from cells. Refrigerate and transport serum after removal from cells. Proper collection and transport of specimen is critical to the outcome of the test. Quantities less than 3 mL may affect the sensitivity of the test. If Cryoglobulin Qualitative is positive, then Immunofixation Electrophoresis Typing and Quantitative IgA, IgG and IgM will be added. Additional charges apply.
