Recombinant anti-PGL-I IgM dilution series in buffer using PGL-I QURapid. A dilution series of the custom-made anti-PGL-I IgM was applied to the PGL-I QURapid. Each dilution was tested in triplicate. Ratio (R-)values (Y-axis) were calculated by dividing the peak area of the test line (T) by the peak area of the flow control line (FC). Mean values and standard deviations are shown. The orange and red dotted lines represent the cut-off for seropositivity (R ≥ 0.16) in serum and FSB (R ≥ 0.12), respectively
