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.

Specimen Requirements
Collection
Collect specimen in a lavender top or ACD (solution B) tube. Centrifuge, aliquot plasma into a plastic screw-cap vial and freeze within 24 hours of collection.
Alternate Specimen
Serum is acceptable for Genotyping but may observe a reduced viral quantitation value. Collect blood in sterile tubes with no anticoagulants; serum separator tubes (SSTs) are recommended. Allow blood to clot at room temperature and separate serum from cells within 2 hours of collection. Transfer serum to sterile, plastic screw-capped, aliquot tubes and store at -18 C or colder.
Normal Volume
2 mL EDTA or ACD plasma
Minimum Volume
0.6 mL EDTA or ACD plasma
