High resolution HLA typing is preferred for matching of bone marrow transplant donors and recipients. Other clinical indications may require high resolution typing to rule out alternative allele combinations.
High resolution Typing for HLA Class I will meet the following criteria: All ambiguities within exons 2 and 3 (which defines the antigen recognition site) and exon 4, will be resolved. Those ambiguities that remain will be reported as an allele code.
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.
Lavender-top (EDTA) tube
Maintain specimen at room temperature; protect from extreme heat or cold. Do not freeze.
Causes for Rejection
