A member asked:

Can an ra test (rhematoid factor) come up negative when a person is not experiencing a flare up at the time?

A doctor has provided 1 answer

Very rarely: Complete remission may rarely cause a positive rheumatoid factor to revert to negative. However, the titer of rheumatoid factor does not really correlate with disease activity in any one person.
