Test Details

Methodology

Chemiluminescent Immunoassay (CLIA)

Result Turnaround Time

1 - 2 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.

Use

This panel utilizes FDA-cleared assays following the modified 2-tier testing (MTTT) algorithm to aid in the diagnosis of Lyme disease in individuals with clinical signs and symptoms consistent with Lyme disease. Lyme disease should be considered based on the presence of typical signs and symptoms of infection in patients with a history of possible exposure to infected ticks.

Special Instructions

Specimens are tested using an immunoassay measuring total antibodies to specific borrelial proteins; if reactive, the specimens reflex to separate IgG and IgM immunoassays targeting additional Borrelia burgdorferi proteins.

Limitations

Screening of the general population should not be performed. The positive predictive value depends on the likelihood of Lyme disease being present. Testing should only be performed on patients with clinical symptoms of Lyme 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.
