Figure 1From: Influenza A viral loads in respiratory samples collected from patients infected with pandemic H1N1, seasonal H1N1 and H3N2 virusesM transcript standard curve for quantitative detections of the pandemic A/H1N1 (A), seasonal A/H1N1 (B) and seasonal A/H3N2 viruses (C). The standard curve of M RNA copy numbers was generated by plotting the Ct value (X-axis) against log10 copy numbers of M transcripts (Y-axis). The amount of M copy number in clinical specimens was obtained by extrapolation of the Ct of the test sample against the standard curve.Back to article page
