Quote:ANA? RF? What are those? Lupus...we haven't talked about at all. Does it sound like it could be? Seriously, I am open to any possibilities.
ANA is Anti-Nuclear Antibodies, RF is Rheumatoid Factor (aberrant antibodies produced in rheumatoid arthritis). Both are common tests in animals suspected of having systemic lupus erythematosus.
If money's really not an issue, how close are you to East Lansing? There's a vet school at MSU. Not cheap, but you should have access to a hell of a lot of diagnostic capability and experience there.
