From: Decision tree for accurate infection timing in individuals newly diagnosed with HIV-1 infection
Assay results in function of time since collection of the first sample for 6 demonstrative patients. a represents the evolution of the markers in a representative patient (PO) and the b to f represent the evolution in all patients with at least one outlier result. Black stars: absence of p31 antibodies; black triangles: presence of p31 antibodies. Blue circles: BED CEIA results, open circles: recent infection, solid circles: long term infection. Red diamonds: LAg-Avidity EIA results; open diamonds: recent infection, solid diamonds: long term infection. Black line: evolution of the viral load. Squares on top of the graphs represent the results obtained when following the decision tree, yellow: very early infection, orange: early infection, green: recent infection, purple: long term infection and brown: advanced infection
