Are you wondering what seronegative rheumatoid arthritis means and how it differs from seropositive RA?
Seronegative RA means that certain antibodies — called anti-CCP (anti-cyclic citrullinated peptides) and rheumatoid factor (RF) — are not detectable in your blood. It accounts for about 20% of RA cases, making it less common than seropositive RA. How is it diagnosed?
Since blood tests for antibodies won't confirm the diagnosis, doctors rely on other methods:
- A thorough medical history and physical exam
- Imaging like X-rays or ultrasound to check for joint damage and inflammation
- Blood tests measuring inflammation markers like CRP and ESR
- Tracking symptoms such as joint swelling, morning stiffness, and fatigue Symptoms to watch for:
- Joint pain, swelling, or stiffness (especially in the morning)
- Fatigue and general weakness
- Symmetrical joint involvement (same joints on both sides)
- Skin changes in some cases
One myRAteam member shared, "I'm in pain and fatigued all of the time," describing their experience with seronegative RA symptoms. Treatment options are largely the same as for seropositive RA and may include:
- NSAIDs (like ibuprofen or naproxen)
- DMARDs (like methotrexate)
- Biologics
- Corticosteroids (like prednisone)
Some evidence even suggests people with seronegative RA may respond *better* to traditional RA treatments. Early treatment is key to protecting joint function, so staying in close contact with your rheumatologist is really important.
