Antibodies are part of the body’s immune response. Tests look for two types of antibodies, known as immunoglobulin M (IgM) and immunoglobulin G (IgG).
When to use IgG and IGM for Lyme disease?
The IgG and IgM WB should always be used when the Lyme IgG/IgM antibody serology has returned an equivocal or positive result.

What is the name of the antibody test for Lyme disease?
IgG antibody test: tests for the IgG antibody that fights bacterial infection ELISA: stands for “enzyme-linked immunosorbent assay,” which detects antibodies in your bloodstream Western blot: a follow-up test that detects proteins and antibodies in the blood The IgM and IgG tests are performed first.

Contrary to what many insurance companies believe, the IgG and IgM Western Blot for Lyme disease are not the same test. Some companies will deny one and pay the other, claiming they are the same test or duplicative of one another. IgG and IgM are two completely different antibodies.

Are there blood tests to detect Lyme disease?
Testing for Lyme disease at the laboratory. A series of laboratory tests can detect Lyme disease antibodies. These tests include: IgM antibody test: tests for the IgM antibody present in the blood when you have an infection. IgG antibody test: tests for the IgG antibody that fights bacterial infection.
When to disregard a positive Lyme disease test?
Some tests give results for two types of antibody, IgM and IgG. Positive IgM results should be disregarded if the patient has been ill for more than 30 days. New tests may be developed as alternatives to one or both steps of the two-step process. Before CDC will recommend new tests, they must be cleared by the Food and Drug Administration (FDA).

I also have read that IgM P23 is an ab ONLY linked to Lyme, so it’s the most important IgM for a positive Lyme diagnosis. However, I have also been diagnosed with Hashimoto’s thyroiditis, which is an autoimmune disorder of the thyroid.
