Molecular Assay, Solid Phase Assays
PRA indicates the degree of reactivity of tested serum in terms of percent of positive reactions when tested against a panel of known HLA phenotypes.
For positive results, the report will define the detected HLA antibody specificities. For negative results, 0% PRA will be reported.
* Reference ranges may change over time. Please refer to the original patient report when evaluating results.

The Class I & II screening assay is performed first and detects the presence/absence of HLA antibodies. If the screening assay is positive, a high specificity and sensitivity single HLA Antigen assay will be performed to identify the specificity of the anti-HLA antibody present in the serum sample from the recipient. By ordering this test the clinician acknowledges that additional reflex testing will be performed and billed at a separate additional charge if indicated.
