Test Details
Methodology
Anaplasma phagocytophilum, Ehrlichia chaffeensis, and Babesia microti by IFA; Borrelia burgdorferi by CLIA
Result Turnaround Time
1 - 4 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
Test Includes
Lyme Total Antibody CIA, Babesia microti IgG, Ehrlichia chaffeensis IgG and Anaplasma phagocytophilum IgG
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.
Limitations
Screening of the general population should not be performed. The positive predictive value depends on the likelihood of tickborne disease being present. Testing should only be performed on patients with clinical symptoms of tickborne disease or when exposure is suspected. In general, IgM tests should be disregarded if the patient's symptoms have lasted more than 30 days. If the patient has been sick longer than 30 days, only IgG results should be interpreted. Potential assay interference due to circulating antibodies in patients with Human Ehrlichiosis (HE) and Tick-borne Relapsing Fever (TBRF), Babesiosis, Parvovirus, and EBV infections has been found. Interpret results from these patients with caution.
For Babesia microti Antibodies, IgG and IgM [138315]: This test was developed and its performance characteristics determined by Labcorp. It has not been cleared or approved by the Food and Drug Administration.
