This test is intended for use in conjunction with clinical presentation and other laboratory markers of disease progress for the clinical management of HIV-1 infected patients. The test can be used to assess patient prognosis by measuring the baseline HIV-1 RNA level or to monitor the effects of antiretroviral therapy by measuring changes in EDTA plasma HIV-1 RNA levels during the course of antiretroviral treatment. The emergence of integrase drug resistance mutations has been observed in vitro and in patients experiencing virologic failure on Raltegravir in clinical trials. Twenty three percent of patients receiving Raltegravir in a clinical trial experience virologic failure at 48 weeks and genotypic analysis detected raltegravir associated resistance mutations in 68% of virologic failures. This assay amplifies and sequences the HIV-1 integrase gene and reports mutations at positions associated with integrase inhibitor drug resistance.

Do not freeze whole blood or any samples stored in primary tube.
Freshly drawn specimens (whole blood) may be stored at 2-25 degrees
C for up to 24 hours prior to centrifugation. Separate plasma from
cells within 24 hours of collection by centrifugation. Follow
manufacturer's instructions for collection tube handling.
