Figure 3From: A cost effective real-time PCR for the detection of adenovirus from viral swabsComparison of the positive results obtained with virus culture and the two molecular assays. A) In each field of the Venn diagram, the number of positive specimens is given. *All virus culture-negative/PCR-positive specimens were resolved as true positives by a commercial DNA extraction and real-time PCR. B) The Cp values obtained by real-time PCR in 27 adenovirus-positive specimens following homogenization- or nucleic acid extraction-based protocols displayed a correlation of 97.6% (solid line). The dashed line represents a correlation of 100%. The dotted oval highlights Cp values obtained with specimens that were PCR-positive but culture-negative.Back to article page
