Elevated RF in serum?

Hello all,

I was wondering if someone could lend their knowledge to interpret my lab results.

Long story short, I was diagnosed with MS earlier this year. I am going to see a new Doctor that is quite some distance away from me and she requested that I have a few lab tests completed before my visit.

I had the tests done but have yet to see the Dr.

Here are some of the results

Serum Proteins
IGA 4.47 g/l
<1 C reactive

Rheumatoid Factor 21 IU/ml

Seeing as my RF is elevated, i figured posting it in this forum would turn up the best results.

Any insight would be greatly appreciated.
