Can An Ra Test False Negative?

Can An Ra Test False Negative?

Recently, a foot doctor said I had rhematoid arthritus. I tested "negative" for RA. He still says I have RA. Saw two more doctors who put a lot of stock in the test and have diagnosed me to not have RA. The foot doctor insists all the signs are there and that, even though the test was negative, he believes I have RA. Is this possible?


The process of diagnosing RA can be a bit tricky and isn't just limited to the results of a blood test. If you click on ths link (the blue highlighted text), you'll find an article on the RA test and the criteria for diagnosing arthritis that might be helpful for you. If you believe the foot doctor is right, keep going back to your doctor, ask for a referral to a rheumatologist and hopefully, you'll get the answers you need.

Good luck!
