Lyme disease tests look for signs of infection in a sample of your blood or cerebrospinal fluid (CSF). CSF is a clear liquid that flows in and around your brain and spinal cord. The test checks your sample for antibodies that your immune system makes to fight the bacteria that cause Lyme disease.

Lyme disease tests are used to find out if you have a Lyme disease infection. Your health care provider is most likely to order the test if you have symptoms that could be Lyme disease, and if you were exposed or possibly exposed to infected ticks.
