Hi DEBMAR: You are what is referred to as seronegative, as am I. This just means that at the PRESENT time, the RA factor is not detected in your blood. You may become positive at some future time, but this is unimportant in the diagnosis of RA. Blood work is not used to diagnose RA, but can be useful in confirming it. The diagnosis is made by the patients H&P, or history and physical. Good luck with your treatment and hang in there
