Does the RTRI work among persons with HIV-2?
The RTRI was developed for the detection of recent HIV-1 infection. The long-term line of the test includes only HIV-1 specific antigen. Therefore, the RTRI cannot be used to detect recent infections among HIV-2 positive persons.If used in geographical areas where HIV-2 is prevalent (or if HIV-2 infection is suspected), it is important to perform type-specific diagnosis using Geenius or similar test before final recent infection classification can be made. However, the diagnostic verification line or test line does detect both HIV-1 and HIV-2.
