How good is testing for Lyme disease?

The accuracy of any test for Lyme disease depends upon the stage of disease. Blood testing for Lyme disease has poor sensitivity in the early stages of disease. Poor sensitivity means some people who have the disease will get a negative test result. CDC has long recommended that patients in the early stages of the disease be diagnosed and treated without the delay and expense of lab testing.

During later stages of disease, currently available testing methods have very good sensitivity (97% to 100%). If you think you might have Lyme disease, talk to your doctor.
