Recent infection: Hi. IgM is present only with recent infection. After IgM levels fall away, IgG takes over for ongoing and recurrent exposure to antigen. (The antibodies in this picture are IgG's). I'm glad your doc was on the ball. She/he may have saved you a world of hurt by making the diagnosis promptly. Good luck! ...Read more

Not enough info: This test is not evidence of lyme but also not proof you don't have it! ultimately lyme is a clinical diagnosis. 20-30% of those who have it never have a positive western blot. It's really important that the test include the 31 & 34 bands & most labs don't check it- igenex is the best lab for a thorough test. See a doc who uses igenex as that is someone able to make a proper diagnosis.See comment:. ...Read more

What is the difference in testing an IgG and IgM bands for Lyme versus multiple myeloma?

Different Diseases: Lyme and multiple myeloma are two very different diseases which are not likely to be confused for one another on a test like this. Igg and igm are two different types of proteins made by the immune system, and within each category you have thousands of different proteins in your body. For lyme, the test looks for a protein that proves your body has "seen" lyme organisms before. ...Read more

Igm is negative but IgG is positive for Lyme disease, what to do?

Old Infection: This most likely means you had an old infection with lyme disease. Our bodies make IgM early in an infection and IgG later. Even once the infection is gone there will be detectable IgG for quite some time. This is part of how our body remembers previous infections so we can fight them off better if we get them again. ...Read more
