Fig. 2From: Strategy using a new antigenic test for rapid diagnosis of Streptococcus pneumoniae infection in respiratory samples from children consulting at hospitalCorrelation between qPCR assays and RDT. The approached quantification using ply (a) or lytA (b) quantitative PCR assays, as evaluated by cycle threshold (Ct), was correlated to the results obtained with the PneumoResp Rapid Diagnostic Test (RDT) on undiluted and diluted respiratory specimens found either negative or positive. The green bar corresponds to the median and the blue bars to the 95% confidence interval. CFU: colony forming unitBack to article page
