What tests are done to check for Lyme disease?

• Enzyme-linked immunosorbent assay (ELISA) test. The test used most often to detect Lyme disease, ELISA detects antibodies to B. burgdorferi.
• Western blot test. If the ELISA test is positive, this test is usually done to confirm the diagnosis.

What blood test shows Lyme disease?

The Lyme disease blood test looks for antibodies in the blood to the bacteria that causes Lyme disease. The test is used to help diagnose Lyme disease. Lyme disease is caused by a bacterium called Borrelia burgdorferi. It is known as a spirochete because of its long, corkscrew shape.

How many tests are there for Lyme disease?

CDC currently recommends a two-step testing process for Lyme disease. Both steps are required and can be done using the same blood sample. If this first step is negative, no further testing is recommended.

Can a urine test detect Lyme disease?

This urine-based test provides more sensitive direct detection for Borrelia burgdorferi infection at all stages of Lyme disease than standard methods. Prior research shows that a small amount of Outer surface protein A (OspA) antigen is detectable in the urine of Lyme disease patients.

Will a CBC show Lyme disease?

The term “chronic Lyme disease” is sometimes used to describe a number of later stage syndromes, but lacks a consistent definition. It is occasionally applied to cases in which patients have late neurologic Lyme disease — neuroborrelosis — but such patients have active infection and fall within stage 3.

How accurate is Lyme disease test?

A tricky diagnosis In the first three weeks after infection, the test only detects Lyme 29 to 40 percent of the time. (The test is 87 percent accurate once Lyme spreads to the neurological system, and 97 percent accurate for patients who develop Lyme arthritis).

How do you test for Lyme disease years later?

Your immune system continues to make the antibodies for months or years after the infection is gone. This means that once your blood tests positive, it will continue to test positive for months to years even though the bacteria are no longer present.

What blood test is used to diagnose Lyme disease?

A blood test for Lyme disease can be done to check for antibodies of the bacteria that causes Lyme disease. The most commonly used test is the ELISA (enzyme-linked immunosorbent assay). A Western Blot test is done to confirm any positive or abnormal ELISA results.

How long does it take to get results from Lyme disease?

If you suspect that you may have Lyme disease there are two options for blood tests available through your G.P. The results of these tests can take from 7 working days to 4 weeks to come back.

What is the most accurate test for Lyme disease?

The most accurate way to detect Lyme disease is with a two-stage blood test. The first is a screening test called an enzyme-linked immunosorbent assay (often referred to as ELISA) that looks for certain antibodies (immune proteins) that are the immune system’s response to the infection.

What are the diagnostic tests for Lyme disease?

Two-tier Testing. The most common diagnostic tests for Lyme disease are indirect ones. They measure the patient’s antibody response to the infection, not the infection itself. The two most-used antibody tests are the enzyme-linked immunosorbent assay (ELISA) and the Western blot.
