a) For the 95 samples with at least one positive CMV test, qPCR results were stratified according to their paired qualitative antigenemia results. Discordant results were not observed above qPCR values of 8500 ge/mL (line).
b) For the 95 samples with at least one positive CMV test, quantitative pp65 antigenemia results were stratified according to their paired qualitative qPCR results. The majority of discordant results occurred with antigenemia values of <2 antigen-positive cells/slide; however, one negative qPCR value had a paired antigenemia result of 62 antigen-positive cells/slide.
