What is difference between igm and igg for western blot for lyme. positive for igm but not igg, what does that mean? tks

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!
