| Specimen Required: |
Collect: 5 mL blood into any chilled container of EDTA, plus 0.2 cc of aprotinin. (0.04 cc aprotinin per mL of whole blood.)
Transport: 1 mL plasma (EDTA plus aprotinin), frozen. (Min: 0.5 mL) Submit specimen in an ARUP Standard Transport Tube.
Remarks: CRITICAL FROZEN. Separate specimens must be submitted when multiple tests are ordered. Immediately centrifuge in a refrigerated centrifuge, separate plasma from cells and freeze ASAP. To prevent analyte degradation, aprotinin inhibitor is the required specimen preservative for this assay. Inhibitor vials are available through ARUP Client Services (ARUP Supply #16570).
