Has anyone else had every blood test remain negative?

    Hi k4rand. On top of the excellent information from Alesandra, I thought you might find this story of interest. My wife, Kelly Mack (a contributor here), was diagnosed almost 40 years ago at the age of two. She had joint replacements as soon as he was old enough and has used a wheelchair since her late teens. At the time of her diagnosis they didn’t even do the rheumatoid factor test. Last year, when doing other blood work, her doctor did the test just out of curiosity and, lo and behold, she is sero-negative. So, even one of the worst RA cases doctors have seen can test negative. Note: Kelly’s CRP is routinely quite elevated, but normal CRP does not preclude RA. Hope you find some answers soon and please know that this community is here for you. Best, Richard (RheumatoidArthritis.net Team)

    Thank you Richard.. the more I’m learning about Sero-negative RA, the more common I’m finding that you can have negative labs.. just frustrated that they haven’t been able to get symptoms under control yet. Feeling hopeful..thank you again for the info.
