Specimen Requirements


Plasma, frozen


3.5 mL

Minimum Volume

1.1 mL (Note: This volume does not allow for repeat testing.)


Ship in a screw-cap polypropylene frozen transport tube or centrifuged PPT™ tubes.


Collect specimen in two lavender-top (EDTA), PPT™, or yellow-top (ACD-A) tubes. Centrifuge specimen within six hours of collection when freshly drawn at 15°C to 30°C. If drawn in EDTA or ACD, the plasma must be transferred to a screw-cap polypropylene transport tube and frozen. If refrigerated, specimen may be held for 24 hours prior to centrifugation. Plasma specimens may be stored at -20°C for 60 days. If longer storage is required, plasma specimens must be stored at -70°C or lower. Ship frozen on dry ice. To avoid delays in turnaround time when requesting multiple tests on frozen samples, please submit separate frozen specimens for each test requested.

Storage Instructions

Freeze; stable for long-term storage. Stable at room temperature for six hours or one day after centrifugation. Stable refrigerated for 24 hours or five days after centrifugation.

Causes for Rejection

Hemolysis; plasma other than EDTA or ACD-A; quantity not sufficient for analysis
