Test Details


Use

Detect antibodies specific for B burgdorferi. This test is intended as the second step in testing serum samples found to have been equivocal or positive using an ELISA or IFA test as the first step to provide supportive evidence of infection with B burgdorferi.


Methodology

Line blot


Reference Interval

Negative


Additional Information

Provides both IgM and IgG Line blot results. Increased specificity reduces cross-reactivity from other spirochetes. Detect and analyze antibodies against specific B burgdorferi proteins. The sensitivity of a Line blot assay by itself is not sufficient to assess Lyme infection adequately. Both EIA and Line blot tests should be performed.
