From: Decision tree for accurate infection timing in individuals newly diagnosed with HIV-1 infection
Results of p31 antibody presence (a), LAg-Avidity EIA (b), BED CEIA (c) and the decision tree (c) in seroconverters. Scatterplots represent the p31 intensity on INNO-LIA strips (a), the normalized optical density for the LAg-Avidity EIA (b), the normalized optical density for BED CEIA (c) and the decision tree classification (d) for 237 samples from 42 seroconverters. The time of the first sample, collected pre-seroconversion, is considered as day 0. Blue diamonds represent classification as recent infection; red diamonds represent classification as long term infection
