Melioidosis DS rapid test: A standardized serological dipstick assay with increased sensitivity and reliability due to multiplex detection
Fig 2
Comparison of Melioidosis DS signal intensities for pooled positive and negative sera over a serum dilution range from 1:6 to 1:107.
(A) Signal intensities for all four antigen bands (T1 to T4) are shown for pooled positive and negative serum respectively. The dipstick assay can easily discriminate between these samples up to a dilution of 1:100 for all spotted antigens (T1 to T4). (B) Exemplary dipstick of pooled positive (top) and negative (bottom) serum. A low intensity control line was present on both test strips, but it is not visible on the photographs.
