Lyme Western Blot IgG
The Lyme Western Blot is a qualitative immunoassay in which antibodies specific to the B. burgdorferi antigens on a membrane strip are visualized. It is a qualitative test and is generally more sensitive and specific than the ELISA and IFA tests. In early or late stage of the disease when antibody levels are very low, western Blot can be positive whereas ELISA and IFA tests can be negative. This test must be used if the Lyme IgG/IgM antibody serology or Lyme IgG/IgA/IgM IFA is positive or equivocal.
