anyone have any information on what could cause a false high IGM (on any pathogen, really, I guess)?
My child is fine (no pans symptoms at all) now, but myco P was checked, to get a baseline . the IgM is very high- almost 5000! the IgG is also high.
I am specifically looking for information regarding how other antibodies can masquerade as myco p. (if they do) or other disorders that may allow an IgM to be so high!
These levels have been checked before, during an exacerbation & her levels were high, then, also, but no where near as high as this!
Also, are the antibody levels quantitative?
she is doing well now & has been for quite a while, so we are counting are blessings, but very curious now.
I know that myco p has been associated with encephalitis, but she is not at that point now at all. She was, but pex, IVig and steroids returned her to us.
