FIG. 3.

Impact of the CMV IgG concentration on the CMV IgG Avidity assay result. Four samples (Smp) precharacterized by the Radim CMV IgG Avidity assay as low or high avidity (two samples at each level) were diluted to six concentrations of specific IgG before testing. % Avi, percent avidity. The error bars represent 1 standard deviation; the horizontal gray field represents the gray zone of the assay; and the vertical gray field represents the target dilution range, into which the final assay dilutes every sample automatically before the avidity of the specific IgG is determined.
