Lyme Disease Check

Lyme disease serology test to detect antibodies against Borrelia burgdorferi.

Lyme disease blood testing screens for antibodies your immune system produces in response to Borrelia burgdorferi — the bacterium transmitted through tick bites that causes Lyme disease. The standard testing protocol follows a two-tier approach: an initial ELISA or immunofluorescence assay (IFA) followed by a confirmatory Western blot if the first test is positive or equivocal. Antibodies typically take 2–6 weeks to develop after infection, so very early testing can produce false negatives. Some functional medicine providers also offer more specialized tests. Early detection and treatment with antibiotics is crucial, as untreated Lyme disease can progress to affect the joints, heart, and nervous system.
