I believe that you should trust the negative tests that you have had! Only the IgM had any reactivity as I read it and that is notoriously inaccurate, so ignore that and only pay attention to the IgG which is negative, right? The IgM test never should have been ordered in the first place. Trust the IgG! It is the most accurate of the two tests.
Please let me know if you have other questions
