Seronegative spondyloarthropathies are defined by which RF status?

Explanation:
Seronegative means the rheumatoid factor test is negative. In seronegative spondyloarthropathies, this RF is typically absent, which helps set them apart from rheumatoid arthritis where RF is often positive. This group includes conditions like ankylosing spondylitis, psoriatic arthritis, reactive arthritis, and arthritis associated with inflammatory bowel disease. The absence of RF isn’t the only clue, but it’s the defining serologic feature. Positive ANA isn’t what defines these diseases, and elevated uric acid points more toward gout, not seronegative spondyloarthropathy.
