are you asking me what causes a positive IgM test? I honestly have no idea. It is just such an unreliable test with so many false positives! But whatever you do, don’t get another IgM test. The IgM is a type of antibody that sometimes come up early in infection for other disease states. But in the case of herpes, it is often present with old infection as well as new infection and the test is often falsely positive as well. Please try to ignore it.
