Ebv igg extremely high positive, low positive rhumetoid, sed rate. i have also significantly high alt. what could it be? i'm referred to rhumetology

Many possibilities: Ebv igg levels by themselves have little significance (except that you have had infectious mononucleosis at some time). A low positive rheumatoid factor is also quite non-specific. The ESR is simply a measure of some form of inflammation if highly elevated, and the alt, if coming from your liver may signify any of a dozen or more causes. A good general internist, or rheumatologist will resolve.

Anything: Ebv igg just means that you have been exposed to mono in the past. It doesn't mean anything recent- that's igm. With positive rheumatoid factor and sed rate, the question is whether or not you have rheumatoid arthritis. I'm not sure how the alt fits in- that is showing liver inflammation which would be unrelated.
