Right, so I am aware of what you were saying about the tests and past infections etc and that the me/cfs dr's look at whether the levels are high. Normally they don't give the levels at all in NZ just positive or negative. So specifically what I'm unsure about is the response in the email where he said "I’ll email you back the raw quantitative results. Please note that CMV IgG will be in arbitrary Abbott units, EBV IgM will be a Sample/Cut-off ratio" - I'm unsure if that information will be adequate for telling me whether the levels are high. I'm unfamiliar with "abbot units" or if there will be anyway for me to tell what is considered high by looking at it. I'm also unsure of what he means by the "EBV Igm Will be a Sample/Cut off ratio" and whether that is going to be adequate for knowing whether the levels are high. So I'm just wondering if you think these test would be worth doing if that is the information they will be giving me.That is the case with all ME/CFS doctors: they use the antibody levels (titer or index level).
Just being positive and low on an antibody test means you may have caught the infection in the past, and the infection is now dormant, or the infection has been entirely eliminated from the body. People typically maintain residual antibodies even decades after catching an infection. So positive and low means a past infection.
But if it is positive and high, then that signifies that you may have an active infection, and thats what ME/CFS specialists want to know.
Which information, and adequate for what?
