 The objective of this study is to evaluate the feasibility of using fresh oral fluid specimens, from known HIV-positive individuals, to test for HIV-1 antibodies using both the DPP HIV 12 and HIV 12 STAT-PAK tests. Two oral fluid collection devices will be used and compared MPC and Chembio collection devices and the results obtained from oral fluids will be compared with those obtained from whole blood and plasma using paired samples from the same participants. The comparison between oral fluid, whole blood and plasma will be made in both Chembio devices HIV 12 STAT-PAK and DPP HIV 12.
