Ladies,
Because of this conversation, I got out the lab report that my great rheumy gave me in 2009.
My RNP was 117 and that was flagged as High. The JO-1 antibody was 18 and also flagged as high.
I had both of the antibodies for Sjogren's flagged - SSA 159 and SSB 22
The Smith antibody, which I think indicates Lupus, was flagged - 28

I'm definitely seeing why my doc in Texas said MCTD. The thing for me is that my current rheumy wants to dismiss all of those results because my more recent labs don't show all of that. (Can you say meds are working? - Duh!)
When I asked about polymyositis or myositis, she just dismissed it. (She thinks I read too much.)
So now you've got me wondering about those again!

I probably won't get good answers until I move back to San Antonio - sigh!
Hugs,
Marla
