This Lyme disease blood test follows the CDC-recommended two-step process to detect IgM and IgG antibodies to Borrelia burgdorferi, the bacteria that cause Lyme disease. If the initial test is positive, a second confirmatory test is automatically performed using the same blood sample.
Lyme disease is a bacterial infection transmitted through the bite of infected blacklegged ticks (commonly known as deer ticks). Ticks typically become carriers by feeding on infected animals like deer or small rodents. For transmission to occur, an infected tick must be attached to a person for 36 to 48 hours.
