Test Overview

Test Methodology

Test Usage

Abacavir hypersensitivity has been shown to be associated with HLA-B*5701. The FDA has issued a recommendation that all patients should be screened for the HLA-B*5701 allele before starting or restarting treatment with Abacavir (Ziagen) or Abacavir-containing medications. Treatment with an Abacavir-containing regimen is not recommended for HLA-B*5701 positive patients.

* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
