Specimen requirements | |
|---|---|
| Patient preparation | None Specified |
| Preferred specimen(s) | Whole blood in a full EDTA (lavender-top) tube and Whole blood in a full EDTA (pink-top) tube and 7 mL serum |
| Minimum volume | 0.5 mL microtainer or 1 mL EDTA (lavender-top) • 0.5 mL microtainer or 1 mL EDTA (pink-top) • 5 mL serum |
| Collection instructions | EDTA (lavender-top and pink-top): Maintain specimen at room temperature. Do not refrigerate. Traumatic draw can introduce thromboplastin and trap WBC and platelets. Refrigeration can precipitate fibrin and trap WBC and platelets. HIV serum: Collect in a serum separator tube or red-top tube (no gel). The tube should be centrifuged after clotting. Spun serum separator tubes may be submitted at room temperature or refrigerated unopened without transfer to a plastic screw-cap vial. Red-top tube (no gel) serum should be transferred to a plastic screw-cap vial and submitted for testing. Submitted tubes must be labeled with patient identifier and submitted only for HIV testing. Dietary supplements containing biotin may interfere in assays and may skew analyte results to be either falsely high or falsely low. For patients receiving the recommended daily doses of biotin, draw samples at least 8 hours following the last biotin supplementation. For patients on mega-doses of biotin supplements, draw samples at least 72 hours following the last biotin supplementation. |
