The TBRF Broad Coverage Antibody Assay (BCA) is a qualitative test designed to detect IgM and IgG antibodies to TBRF Borreliae group-specific antigens in human serum. A positive test suggests exposure to the TBRF Borreliae group, and should be used in conjunction with patient clinical symptoms and history. The BCA Assay is a simple and cost-effective test, which gives either a positive or negative result.

Principle: Detects IgM and IgG antobodies to the TBRF Borreliae group, and a positive test suggests exposure to the TBRF Borreliae group, and should be used in conjunction with patient clinical symptoms and history. For specific protein or band information, an ImmunoBlot IgM or IgG test should be ordered to provide more information and possible speciation of the Borrelia. The sensitivity of the TBRF Borrelia BCA Assay is greater than 90%, and the specificity is greater than 94%.
