Q: hi, i have done a lab test for western blot and both 58 kd (igg) band and 93 kd (igg) band are reactive. do i have lyme disease? thank you?

: The CDC requires 5 out of 10 bands for a positive test. For IgG, 5 of the following ten bands have to be positive: 18, OspC (22-25), 28, 30, 39, 41, 45, 58, 66 and 93. However, if you have other clinical features which are associated with chronic Lyme disease, you may be diagnosed of having the disease with those 2 positive bands.
