Test Overview

Test Methodology

Polymerase Chain Reaction (PCR)

Test Usage

The high replication rate of HIV-1 coupled with its rapid mutation rate drives the accumulation of mutations, some of which confer reduced susceptibility to antiretroviral agents. HIV-1 Genotyping identifies mutations in the HIV-1 reverse transcriptase and protease genes. Genotyping can be used to identify mutations associated with current or evolving resistance and monitor transmission of drug-resistant HIV-1.

Reference Range

Interpretive report provided.

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