I've picked up my med. reports to take the the rheumatologist. There are some tests that show low. Does anyone know what the mean, please :?) RBC L(red blood count?) Hgb L Hct L aldolase Normal, top high end of the range I know they have to do with blood counts, but not what. Do they pertain to CFS? Everything else, except for thyroid, and cholesterol were ok.
