Figure 3. — Photochemical treatment (PCT) inhibition of parvovirus B19 (B19) amplification in plasma using a preamplification quantitative polymerase chain reaction assay. Log inhibition is graphed according to amplicon length of preamplification. With increasing preamplification amplicon length, the greater the amount of log inhibition is detected. An amplicon length of >3 kb was required to detect the full log inhibition in this assay.
