27. Which bands normally show up first on a Western Blot test? Which bands are specific for Lyme disease? Which bands normally appear after the patient has had Lyme for at least one year?

The first Western Blot band to show positive is normally the 41KD band followed intermittently by the 23KD band. Bands 18KD, 23-25KD, 31KD, 34KD, 37KD, 39KD, 83KD and 93KD are specific for indicating Bb (Borellia burgdorferi) exposure. The problem is they may not show up early in the infectious stages or may not appear for a year or more, or they may not show up at all. The ILADS 2002 Guidelines state that the presence of the 41KD band along with one of the specific bands listed above indicates a person has been exposed to Lyme disease.
