Test Comments:
Please note: The following comment will appear on the report when IgG is NEG and IgM is POS. Caution must be used in supporting a diagnosis of B. burgdorferi infection, when sera are Western blot IgM positive and Western blot IgG negative after the initial 4-week period from onset. Because the likelihood of a false-positive test result is high for these individuals, a positive IgM test alone is not recommended for use in determining active disease in persons with illness of longer than one
month's duration.
IgG Western Blots which have 5 (or more) of the 10 significant bands are considered positive for specific antibody to B. burgdorferi. (Proceedings of the Second Conference of Lyme Disease, Dearborn, Michigan, 1994.)
IgM Western Blot strips which have 2 (or more) of the 3 significant bands are considered positive for specific antibody to B. burgdorferi. (Proceedings of the Second Conference of Lyme Disease, Dearborn, Michican, 1994.)
Methodology:
Western Blot
Clinical Significance:
Lyme disease is transmitted by a tick vector carrying Borrelia burgdorferi. Immunoblot testing qualitatively examins, with high specificity, antibodies in a patient's specimen. Immunoblot testing is appropriate for confirming a detected EIA or IFA test result.
