*Initial tests were done from samples obtained at enrolment (i.e after a negative rapid HIV test result). HIV VL tests (including follow-up) were done first to confirm infection, and all the serology tests were done later. Pt ID = participant identity, F = female, M = male or married, S = Single, D = divorced, gen = generation, ELISA = enzyme-linked immunosorbent assay, W. Blot = Western Blot, LAg = limiting antigen, F/U = follow-up, Insuf = insufficient, ND = not done (participant did not come for follow-up), n/a = not applicable, + = positive, - = negative, --- = not available. Units: HIV VL = copies/ml; p24 antigen = cut-off index (COI); Genscreen ELISA = sample cut-off (S/CO); LAg avidity = normalized optical density (OD-n); CD4 count = cells/μl.
