To identify further Western blot bands that may be specific in the diagnosis of
The Borrelia burgdorferi antibody profiles of 270 western blot positive patients and 241 western blot negative patients from 2008 were examined.
27 different non-specific bands were detected in both groups. Six of 27 (22%) of the non-specific bands were detected significantly more in the western blot positive patients compared to the western blot negative patients (20 kDa, p<0.0001; 28 kDa, p<0.002; 36 kDa, p<0.002; 37 kDa, p<0.007; 48 kDa, p<0.023; 56 kDa, p<0.028; two-tailed F test).
Results suggest that the 20, 28 and 48 kDa bands should be regarded as specific.
