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.
Frequently Asked Questions about Tick-borne Illness Testing How is Lyme disease diagnosed? Lyme disease is a clinical diagnosis based on history, symptoms, and exposure to a tick bite. Some patients show a rash, but in many cases a rash is not apparent. For this reason, laboratory testing is an important aid in diagnosing Lyme disease. Like many tests for infectious diseases, the Lyme tests measure antibodies in a patientâs blood.
