Causes for Rejection
Insufficient volume of DNA
To avoid possible adverse reactions, this test has been recommended for patients who may be prescribed Carbamazepine and oxcarbazepine. Two HLA alleles are associated with adverse reactions to these drugs. The alleles are HLA B*15:02, which is more common in individuals of Asian descent, and HLA A*31:01, which is more common in individuals of European descent. This test evaluates the presence or absence of these alleles.
A negative test result does not rule out an adverse reaction with the drug Carbamazepine and oxcarbazepine. Even with approproate precautions, an occasional specimen may not be satisfactory for testing. In such cases, an additional specimen should be collected for retesting.
This test was developed and its performance characteristics determined by LabCorp. It has not been cleared or approved by the Food and Drug Administration.
Sequence-based typing (SBT or NGS), sequence-specific oligonucleotide probes (SSOP), and/or sequence-specific primers (SSP) as needed to obtain a high resolution typing
