Hopefully your Dr can help with this question! I'm not sure myself!! Good luck & I wld love to hear what you find out;) Have a good week!!!😊

I have Sero Negative RA….When given that diagnosis at first, when I saw the word “negative” I thought I didn’t have RA…..Since then one of the articles on this site explains the difference but if I remember correctly, it didn’t mention whether it can switch from one diagnosis then the other….I’m sure your Rheumy can explain what going on…..Good Luck👍🏼👍🏼👍🏼❤️❤️❤️

I was originally diagnosed as seropositive and later it was changed to seronegative. I believe it was all based on blood work that was done (RA factor and CRP) and maybe others. I have been told that seronegative it treated with the same drugs as seropositive. At least I am being treated that way. Hope this helps.

I thought ONLY from Sero-Negative to Sero-Positive. Check on Google

I disagree, you can be seronegative or positive on your 1st testing.
