Performance of the nine RSTs/STs on the panel of PHI samples, classified according to the WB profiles.

The performance of seven 3G RSTs/STs and two 4G RSTs/STs (underlined in grey) was evaluated on a panel of 50 reconstituted whole blood samples from 50 patients during the PHI stage. The number of western blot lines are reported. The tests bought on websites are shown in bold. For the HIV Combo (Alere) test, the detection of p24Ag is performed with a specific line, distinct from the antibody line; we report the combined (Ag + Ab) result. A positive result was assigned to the sample if either the HIV-1 or HIV-2 line was positive for the HIVTOP and BioTechMed HIV1/2 Rapid-4 tests. The positive (in white) or negative result (in black) is represented for each sample.
