Can I be negative for most tests and have RA?

Ander35

I have joint stiffness, muscle/tendon pain and severe fatigue after covid vaccine (may be coincidence dont know yet. I have hashimotos thyroid as well.

Doc tested me for autoimmune diseases. I am negative RA Factor, negative ccp negative ANA. However my ETA 14.3 is .2 or "weak positive"

Does this definitely rule out autoimmune disease? Or does the eta mean I may have early RA?

Any input is welcome
