Polymerase Chain Reaction (PCR) • Next Generation (ultra-deep) Sequencing
See Laboratory Report
This panel will assist clinicians to evaluate virologically suppressed patients for antiretroviral regimen modification when there is insufficient historical viral RNA resistance and viral tropism information. This test utilizes PCR and next generation (ultra-deep) sequencing of proviral DNA to detect drug resistance mutations in the HIV-1 protease, reverse transcriptase and integrase genes. As the CCR5 antagonist maraviroc may also be considered as a component of a new regimen, this panel includes the requisite tropism test performed on proviral DNA.
