The correlation of HIV-1 boosted p24 antigen and HIV-1 RNA quantification (Amplicor Monitor; Roche) for 160 frozen plasma samples of known viral load at a 95% confidence interval by Spearman rank correlation and analysis of variance was r = 0.671 (R2 = 0.450; P < 0.01) (a) and that for 80 blinded fresh plasma samples at a 95% confidence interval by Spearman rank correlation and analysis of variance was r = 0.782 (R2 = 0.612; P < 0.01) (b).
