ADAMTS13 Evaluation is a reflexive testing algorithm. Activity is always performed. If activity result is <= 30%, the inhibitor assay (1297) will be performed. If inhibitor result is <= 0.7 Inhibitor Units, the antibody assay (1299) will be performed.
Additional Test Information
Citrated Plasma (light blue top)
Additional Sample Requirements
Citrated plasma (preferred), serum, or whole blood (light blue or red top tube) stored at room temperature or refrigerated up to 7 days is acceptable. Whole blood must be centrifuged and plasma or serum sent for testing. EDTA samples are not acceptable.
