I see you got a great answer and Totally I agree. Yes - they can be connected.
I'm not on birth control and antibiotics.
I've had a high RA Factor for at least 3 years. I was just diagnosed with Hashi's with my number being 483. How long do you think I could have been wallking around with this and not know? It's a good thing my endo doc gave me the antibody test!
Hmm...would this fit for a one-time positive Rheumtoid Factor as well?
If you are on the birth control pill or on certain antibiotics, you can get a positive ANA panel. I had once been diagnosed as having lupus by a Phys. Asst that thought he knew more than he did, I later had it tested again after being off the birth control pill and all antibiotics, and Voila! No positive ANA. Google ANA panel and check your medications.
