HIV PhenoSense GT
Ordering Recommendation
Intended for use in patients with viral loads ≥500 copies/mL. HIV-1 combined pheno- and genotyping test to provide antiretroviral susceptibility information for protease inhibitors (PI) and reverse transcriptase inhibitors (ie, NRTI and NNRTI). Preferred test for patients with known or suspected complex drug resistance patterns (eg, suboptimal virologic response to treatment and viral load rebound).
