@ccourt, my first instinct would be to include the anti-RNP with the anti-SSa and SSb. The ANA is very non-specific, and usually just leads the doctor to determine that there is an immune condition.
The anti-RNP is more commonly associated with Lupus, but often shows up in Sjogren's, without being paired with the anti-SM that indicates Lupus. It seems to be an indicator of Raynaud's when present in Lupus patients, just as a point of interest.
He may also have meant the Rheumatoid Factor (RF) which, despite its name, is not a specific indicator of Rheumatoid Arthritis. RF shows up in a number of autoimmune diseases when there is joint involvement.
I completely understand the information overload situation, and it sounds like your doctor was experiencing a bit of the same, seeing results he wasn't prepared for!
