HIV-1 combined pheno- and genotyping test provides antiretroviral susceptibility information for protease inhibitors (PI), reverse transcriptase inhibitors (NRTI, NNRTI), and integrase inhibitors (INI). Preferred test for patients with known or suspected complex drug resistance patterns (eg, suboptimal virologic response to treatment and viral load rebound).
Lavender (EDTA) or plasma preparation tube (PPT).
Separate from cells within 6 hours of collection. Transfer 5 mL plasma to ARUP Standard Transport Tubes and freeze immediately. (Min: 3 mL)
CRITICAL FROZEN. Separate specimens must be submitted when multiple tests are ordered.
Ambient: Unacceptable; Refrigerated: Unacceptable; Frozen: 2 weeks
Performed by non-ARUP Laboratory
Procedure should be used for patients with documented HIV-1 infection and viral loads greater than 500 copies/mL.
