I had some blood tests, including Metabolic Panel, last week. One thing I have not seen before was high IGM. I guess that is an immunoglobulin of the "M" variety (there are several). Mine was very high, over 900, which is several times normal. I have no idea if it means just an infection (I have a bad cold) or it means something more serious. I won't have a chance to talk to the doctor until Friday, but I thought maybe someone would know here.

It's cold here and will snow later, so it's just as well to be staying inside now.

Mariel (several diagnoses, including first MS diagnosis 28 year go or so, then Porphyria dx later, now Polycythemia Vera (high platelets and red cells).
