Fig. 2From: Using signal-to-cutoff ratios of HIV screening assay to predict HIV infectionRelationship between HIV screening chemiluminescent immunoassay S/CO ratio and HIV infection. (A) HIV screening assay S/CO ratio in the HIV infection and the non-HIV infection. (B) Correlation between HIV screening assay S/CO ratio and HIV infection status. (C) Correlation of increasing S/CO ratio of HIV screening assay with increasing rate of diagnosed HIV infectionBack to article page
