I know this post is old but I just needed some feedback on my results. I had an IFA HH 6 test done and it here are the results... IGG 1:160 (<1:10) IGM <1:20 (<1:20) So it looks like my IGG was Positive but my IGM was negative. Does this meeting I have a past infection only or could it be a present one as well as I've heard they are hard to detect? I am currently suffering from Chronic Fatigue and MS. Thanks!
