My rheumatologist said I was sero-.. Thanks for all answers or inputs!
My labs showed extremely high inflammation, but not the RA factor. I was diagnosed based on that, medication effectiveness, pain level, and pain type and location.
I have sero-negative negative RA, and it was several hereafter my symptoms began before my inflammatory markers (SED rate and CRP) increased.
Mine too - and invariably when its clinic day I am fit as a fiddle, snuff to make you ill, cos you can walk out of there 4 hours later to find when you get out the car your knee is having a flare up
My mother had RA but for 20 years it never showed up in my blood work. Finally a rheumatologist diagnosed it from LOTS of x-rays, MRI and addition blood work. That was the first time I had heard that not everyone shows up positive in the regular blood tests.
