Lyme disease testing

If you suspect Lyme disease, your doctor may run a Lyme test. Lyme testing is notoriously inaccurate, however, conventional labs are a good place to start. Your doctor may run a test called IgM. IgM is an antibody that shows up with current or recent infection. Therefore, if your infection has been present for more than a few weeks, this test may be negative. If the test is negative, your doctor may say you don’t have Lyme. It is a good idea to ask for a Western Blot test. This test includes IgM as well as IgG, which is an antibody that shows up with any past infection. Past Lyme infections can become chronic, so this test is very useful.
