HLA B*15:02 Phenotype details

What HLA B*15:02 Phenotype shows

The phenotype result gives a plain interpretation of your HLA-B15:02 genotype, typically stating whether you are positive (a carrier) or negative. HLA-B is an immune system gene, and the B15:02 variant is strongly linked to a higher risk of severe skin reactions, such as Stevens-Johnson syndrome, with carbamazepine and some related anti-seizure medicines like phenytoin and oxcarbazepine. Because it comes from your DNA, it is a lifelong result, not a level that changes. A positive result means increased risk, not a certain reaction, and a negative result does not exclude all reactions, so it is weighed by a prescriber alongside other information.
