Testing algorithms for determination of recent (R) and long-term (LT) HIV-1 infections by the (a) LAg and (b) BRAI avidity assays. Dashed arrows in the algorithms indicate that all specimens classified as LAg-pending were reclassified as R because all samples were collected from persons confirmed to be HIV-positive and all BRAI-invalid results were reclassified as R because all samples were collected from individuals who were confirmed to have HIV infection, were treatment naïve and not classified as having AIDS. *BRAI cut-off is the mean of the optical density of the assay negative controls plus 0.250. ODn, normalized optical density.</p
