How long does Lyme IgM stay positive?
IgG antibodies are slower to develop, beginning to show 4-6 weeks after exposure and may peak 4-6 months after exposure. While IgM tends to be associated with an active infection, both IgM and IgG can persist in the blood for many years.
When does Lyme titer become positive?
In this case, if the person is retested a few weeks later, they should have a positive test if they have Lyme disease. It is not until 4 to 6 weeks have passed that the test is likely to be positive.

What organs does Lyme disease affect?
It can affect any organ of the body, including the brain and nervous system, muscles and joints, and the heart. Patients with Lyme disease are frequently misdiagnosed with chronic fatigue syndrome, fibromyalgia, multiple sclerosis, and various psychiatric illnesses, including depression.
At what stages of Lyme disease are the IgG and IgM antibodies elevated?
burgdorferi infection develops slowly, and only one half of patients with early-stage Lyme disease will have a positive serology. The immunoglobulin M (IgM) and immunoglobulin G (IgG) antibodies appear two to four and four to six weeks, respectively, after the onset of erythema migrans and peak at six to eight weeks.
What is the difference between Lyme IgG and IgM?
IgM antibodies usually peak within a few weeks after an infection with Borrelia bacteria and start to collapse 4-6 months after infection. IgG antibodies are slower to develop, beginning to show 4-6 weeks after exposure and may peak 4-6 months after exposure.
Does Lyme disease stay in your body forever?
