HLA Percent Reactive Antibody (PRA) Class I & Class II [Transplant]

Container/Tube Type:

This test requires it's OWN collection tube.

Preferred Collection Container:

SST (Serum Separator)

Also Acceptable Collection Container:

Red (No Additive)

Collection Information:

Collect 5.0 mL of whole blood into a serum separator tube (preferred). This test requires it's own collection tube (sharing between departments is NOT acceptable).

Transport Information:

Allow tube to clot for 30 minutes and then centrifuge and refrigerate. DO NOT SPIN RED TOP TUBES if received unspun. PRA testing requires its own specimen separate and cannot be shared with other laboratory sections. Send original tube.

Minimum Sample Volume: Minimum amount of analytical sample (serum, plasma, urine, CSF, etc.) required to perform an assay once. Submitting the minimum volume makes it impossible to repeat the test or perform confirmatory or reflex testing. In some situations, a minimum specimen volume may result in a QNS (Quantity Not Sufficient) result, requiring a second specimen to be collected.
