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.
A new test that measures T-cell response to antigens from Borrelia burgdorferi has the potential to vastly improve Lyme disease diagnosisâespecially in the early phases. The test, called iSpot Lyme, utilizes the Elispot technology introduced several years ago for evaluation of persistent tuberculosis.
