Clinical Use

Use

This test is used for evaluation of patients with a history of, or suspected, tick exposure who are presenting with fever, myalgia, headache, nausea and other nonspecific symptoms. Evaluation of infection with the most common tickborne diseases found in the United States, including Lyme disease (Borrelia burgdorferi), ehrlichiosis (Ehrlichia chaffeensis), anaplasmosis (Anaplasma phagocytophilum) and babesiosis (Babesia microti).

Special Instructions

If reflex test is performed, additional charges/CPT code(s) may apply. Specimens that are not collected or stored correctly, such as grossly hemolyzed or lipemic samples, may be rejected.

Limitations

Screening of the general population should not be performed. The positive predictive value depends on the likelihood of tickborne disease presence. Testing is indicated only for patients with clinical symptoms of tickborne disease or when exposure is suspected. In general, IgM tests should be disregarded if symptoms persist for more than 30 days; only IgG results should be interpreted. Potential assay interference can occur due to circulating antibodies from other infections like Human Ehrlichiosis (HE), Tick-borne Relapsing Fever (TBRF), Babesiosis, Parvovirus, and EBV. Results should be interpreted with caution in these patients.
