Lyme Disease Ab with Reflex to Blot (IgG, IgM)


Lyme disease is caused by a bacterium borrelia burgdorferi and is transmitted by ticks. EIA is the screening test with high sensitivity for antibody detection. Immunoblot testing qualitatively examines with high specificity antibodies in a patient's specimen. Immunoblot testing is appropriate for confirming a detected EIA test result. 

Tick-borne diseases are caused by infections transmitted to humans via a tick vector such as the deer tick, dog tick, wood tick, and Lone Star tick. In the United States, transmission occurs primarily in the spring and summer months. Causative agents include bacteria (including rickettsia), viruses, and protozoa. The incidence varies by geographic location and causative agent.
