Samples for flow cytometry (including but not limited to absolute and percent CD4+ and CD8+ cell counts) and HIV RNA levels will be obtained at each study visit. The Roche Amplicor 1.5v (LOQ= 50 copies/mL) will be used until the patient has achieved an HIV RNA level < 50 copies/mL at which time the HIV RNA PCR (LOQ=50 copies/mL) assay will be used. It is noted that no testing outside of what is specified in this protocol, will be conducted without additional written informed consent.
