Are there different severities of rheumatoid arthritis?

How do you determine severity of rheumatoid arthritis?

The most complete method of measuring RA severity is based on American College of Rheumatology (ACR) standards [14] and involves clinical assessment (history, physical examination), laboratory tests (e.g. ESR) and imaging procedures (e.g. X‐rays, MRI).

Can you have rheumatoid arthritis with a negative rheumatoid factor?

If you have negative rheumatoid factor and negative anti-CCP and are diagnosed with rheumatoid arthritis, it is called seronegative RA. Occasionally, seronegative RA patients may develop antibodies and become seropositive at a later date — but this does not occur in most cases.

Can you have RA for years and not know it?

In a few people with RA — about 5% to 10% — the disease starts suddenly, and then they have no symptoms for many years, even decades. Symptoms that come and go. This happens to about 15% of people with rheumatoid arthritis. You may have periods of few or no problems that can last months between flare-ups.

What is considered a positive rheumatoid factor?

Reference ranges may vary, but normally values >20 IU/ml are considered positive; however, most RA patients have values >160 IU. As with rheumatoid factor, values >20 are normally considered positive; however, most RA patients will have strongly positive results (i.e., >60 units).

Can rheumatoid factor increase over time?
