Test Details


HLA A antigens may be useful in relation to certain disease states.


Regarding whole blood specimens, an adequate test requires the presence of intact lymphocytes at the time of testing. Even with appropriate precautions, an occasional specimen may not be satisfactory for testing. In such cases, fresh blood should be drawn for retesting.

This test was developed, and its performance characteristics determined, by LabCorp. It has not been cleared or approved by the US Food and Drug Administration (FDA).


Sequence-based typing (SBT), sequence-specific oligonucleotide probes (SSOP), and/or sequence-specific primers (SSP) as needed to obtain the required resolution.
