## Indications for use
The Cambridge Diagnostics Ireland Ltd. Human Lyme Borrelia burgdorferi Western Blot 1gG kit is an in vitro qualitative assay for the detection of antibodies to Borrelia burgdorferi in human serum. It is intended for use in testing human serum samples which have been found positive or equivocal using an EIA or IFA test procedure for Borrelia burgdorferi antibodies. Positive results from this Western Blot assay are supportive evidence of infection with Borrelia burgdorferi, the causative agent of Lyme Disease. The Cambridge Diagnostics Ireland Ltd. Human Lyme Borrelia burgdorferi Western Blot IgG kit can be used at any time following onset of symptoms provided the EIA or IFA is positive or equivocal. It should be used for follow up when: 1) Only IgM antibodies were originally detected, 2) IgG antibodies were detected but were not considered significant by Western blot, or 3) previously tested seronegative individuals are shown to develop antibodies by EIA or IFA tests.
