How accurate is Lyme disease antibody 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).
What is Borrelia burgdorferi antibody?
Presence of antibodies confirms infection with the Lyme Disease spiral bacterium (spirochaete) known as Borrelia burgdorferi by a bite from an infected tick. Patients bitten by an infected tick which is not removed within a day or so may develop Lyme disease.
How can I tell if my baby has Lyme disease?

How common is a false positive Lyme test?
[6] Moreover, specificity as low as 43% is reported, indicating that 57% of results coming from such labs are false positives. In BC less than 1% of people tested for Lyme disease have the infection (personal communication with M. Morshed, 2015).
Can a Lyme test be false negative?
There may not have been time for antibodies to develop; the immune system may be suppressed; or the person may be infected with a strain the test doesn’t measure. Lyme disease is known to inhibit the immune system and 20-30% of patients have falsely negative antibody tests.
How do you test for Borrelia burgdorferi?

- 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.

If this is positive for Borrelia antibodies, the sample is put through an immunoblot test This is also known as a Western blot test. This test measures immunoglobulin G (IgG) and immunoglobulin M (IgM) antibodies in your blood. The CDC also recommends that an approved EIA test may be used in place of the immunoblot test as the second test.

When is serology indicated in the diagnosis of Lyme disease?
In Lyme disease, this means that early acute disease characterized by an expanding rash (erythema migrans or EM) at the site of a tick bite cannot be reliably people will have made enough antibodies that serology is useful for con exposure to stages of Lyme disease.
