Test Overview. A Lyme disease test detects antibodies to the Lyme disease bacteria Borrelia burgdorferi in the blood. Lyme disease bacteria are spread by certain kinds of ticks. Lyme disease can be hard to diagnose because its symptoms are similar to those of many other illnesses.
Diagnosis of Lyme Disease. The diagnosis of Lyme disease must be based on a combination of factors, including history (tick exposure), clinical signs, finding antibodies to B. burgdorferi bacteria, and a quick response to treatment with antibiotics.
