If Lyme Disease Antibody Screen is Equivocal or Positive, Lyme Disease Antibodies (IgG, IgM), Immunoblot will be performed at an additional charge (CPT code(s): 86617 x2).
Immunoassay (IA) • Reflex: Immunoblot (IB)
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.
