HLA B*57:01 Genotype details

What HLA B*57:01 Genotype shows

HLA-B is one of the immune system genes that help your body recognize what belongs to it. The HLA-B*57:01 variant is strongly linked to a hypersensitivity reaction to abacavir, a medicine used to treat HIV, and testing for it before starting abacavir is a standard part of care. This genotype result reports whether the variant was found in your DNA. It is a lifelong genetic result, not a level that changes. A positive result means a much higher risk of this reaction. A negative result lowers the risk but does not remove it entirely, so the result guides a prescriber's choice rather than replacing clinical judgment.
