Clinical Significance
Lyme disease is caused by a bacterium borrelia burgdorferi and is transmitted by ticks. A screening test with high sensitivity is used as the first step in the CDC recommended algorithm. Immunoblot testing qualitatively examines, with high specificity, antibodies in a patient's specimen. Immunoblot testing is appropriate for confirming a detected screening result.
