This test also identifies Lyme disease antibodies and can confirm the results of an ELISA test. This common and rapid test to identify Lyme disease antibodies is the most sensitive screening test for Lyme disease. Enzyme-linked immunosorbent assay (ELISA).There are two types of antibody tests to detect Lyme disease. Finding antibodies to the Lyme disease bacteria does not tell whether you were infected recently or sometime in the past. Once formed, antibodies usually stay in your system for many years, even after successful treatment of the disease. It may take up to 2 months after becoming infected before antibodies can be detected in a blood test. Antibody testing may also be done on fluid from the spine or from a joint.
Antibody testsĪntibody tests are the most commonly used tests to help identify Lyme disease. Other tests may be done in certain situations. Antibody tests can sometimes be used to help identify Lyme disease. If you and your doctor think you have Lyme disease, your doctor will do a careful medical history and physical examination. Lyme disease can be hard to diagnose because its symptoms are similar to those of many other illnesses.

Healthline has strict sourcing guidelines and relies on peer-reviewed studies, academic research institutions, and medical associations. Since it can take several weeks or months before antibodies are found in blood, the Western blot test may not always be reliable. If it causes a change in color, antibodies to a specific infection have been detected.
The proteins are placed onto blotting paper that’s made from a material such as nitrocellulose.Īn enzyme is added to the paper. The Western blot uses a procedure called gel electrophoresis to identify and separate proteins by molecular weight and length. Antigens stimulate your immune system to push out antibodies in an effort to fight the disease. If you develop a viral, fungal, or bacterial infection, your body will produce proteins called antigens in response. The Western blot test looks for the antibodies against an infection, not the infection itself. If you get a positive result for Lyme disease or HIV after taking an enzyme-linked immunosorbent assay (ELISA) test, your doctor may recommend a Western blot test to you. It was invented in 1979 to identify ribosomal RNA binding proteins. The Western blot test is also known as a protein immunoblot test or immunoblotting.
