Can a seronegative RA result change to positive over time?

Yes, it's definitely possible for someone initially diagnosed with seronegative RA to later develop antibodies and become seropositive. Some people with seronegative RA will develop RF or anti-CCP antibodies months to years later in the disease course. It's also worth noting that in early RA cases, antibodies are produced at a slower rate, which can lead to false-negative results initially.

Given that your test was done in 2012 and never repeated, it would be reasonable to request updated blood work to see if your status has changed. Regarding your doctor's skepticism, this is unfortunately a common challenge with seronegative RA. A myRAteam member shared a similar experience: "I have every documented symptom of RA, including high inflammation markers and skin nodules. Still, because the RA blood test was negative, my medical provider insists it is osteoarthritis and won't refer me to a rheumatologist."

Seronegative RA accounts for around 20 percent of RA cases and is more difficult to diagnose because it lacks the typical antibody markers. Diagnosis relies more heavily on:

- Clinical symptoms and physical examination
- Imaging tests (X-rays, ultrasound) showing joint inflammation or damage
- Inflammation markers like ESR and C-reactive protein
- Medical history and disease progression

If you're experiencing RA symptoms and have elevated inflammation markers, these are important diagnostic clues even without positive antibody tests. Regarding scleroderma, it's worth noting that people with seronegative RA may be misdiagnosed with other conditions, and some people can have overlapping autoimmune conditions. If you're not confident in your current care, seeking a second opinion from another rheumatologist who specializes in complex or seronegative cases might help you get clearer answers about your diagnosis and treatment options.
