Can you have a high rheumatoid factor and not have rheumatoid arthritis?

High RF levels can indicate rheumatoid arthritis, but this is only one aspect of a full diagnosis. High RF levels can also occur in people with other conditions and in those with no health issues. Also, in some cases, people with autoimmune conditions have normal RF levels.

Is rheumatoid factor positive in rheumatoid arthritis?

Rheumatoid factor (RF) is used in the diagnosis of rheumatoid arthritis (RA). RF results are positive in approximately 75% of patients with RA, although RF is not etiologically related to RA. High RF titers indicate a poorer prognosis, as patients with higher RF levels tend to have more severe disease.

What happens if RA factor is positive?

Results. A positive rheumatoid factor test result indicates that a high level of rheumatoid factor was detected in your blood. A higher level of rheumatoid factor in your blood is closely associated with autoimmune disease, particularly rheumatoid arthritis.

Can you have RA without testing positive?

People who don’t test positive for the presence of RF and anti-CCP can still be diagnosed with rheumatoid arthritis based on their symptoms, a physical exam of their joints, and imaging tests (X-rays and ultrasounds) that can show patterns of cartilage and bone deterioration.

How accurate is the rheumatoid factor test?

The sensitivity of the rheumatoid factor blood test is 85 percent, which means that 85 percent of the general population can be expected to test negative, but 15 percent might test positive even without having RA.
