As Jennifer said, a positive ANA can mean any AI disease, including RA.
You have to have at least 4 of the 11 symptoms on the "lupus list" (see link in my signature below) to have lupus, and it doesn't sound like that is the case with your son.
Fortunately a rheumatologist is the person who is qualified to treat both RA, Lupus, and several other AI diseases, so you're already in the right hands.
I've never heard of the Slit Lamp Exam before -- it doesn't seem to be associated with Lupus from anything I've been able to locate. It is however associated with another AI disease, Sjogren's Syndrome. (Again something a rheumy would treat.) Is your son having some eye issues?
Try not to worry too much about
lupus, so far I don't hear anything that would make me think anything but RA is present.
