My daughter has recently tested positive for mycoplasma IgM antibodies. In fact, over the past 4 years, she has either been equivocal or weakly positive for this infection. Since I know that false positives can occur, at least according to the Mayo Clinic site, I am wondering if there is some other test that can truly confirm whether the mycoplasma bacteria is present or not. Would a mycoplasma PCR test be the thing one should do if one wants to be truly sure whether mycoplasma is present or not? And, can one have a false positive even to this test?
