Rheumatoid factor (RF) is a type of antibody that is often found in elevated levels in people suffering from rheumatoid arthritis (RA), an autoimmune disease that affects the joints. Measurement of RF levels in the blood is used as a diagnostic tool to identify and assess RA. Rheumatoid arthritis is a systemic and autoimmune disease that affects approximately 1% of the population.

Why should I get a test for Rheumatoid factor (RA)?

  • Early diagnosis: RA can be a progressive disease, and an early diagnosis is crucial to initiate treatment as soon as possible. The earlier the disease is detected, the better the chances of preventing joint damage and reducing symptoms.

  • Appropriate treatment: By determining if you have RA, the doctor can design a treatment plan tailored to your needs. Treatments may include medications and other therapies aimed at reducing inflammation, pain, and preventing joint damage.

  • Improved quality of life: Treating RA can help improve your quality of life by reducing pain, swelling, and joint stiffness, making it easier to perform daily activities.

  • Reducing joint damage: By controlling and treating RA, you can reduce the risk of permanent joint damage and deformities that can occur if the disease is left untreated.

What does an elevated Rheumatoid factor value indicate?

A high RF level can indicate an increased risk of RA and can also be used to monitor the progression of the disease and the effectiveness of treatment in individuals with RA.

Inflammation is a biological process that functions as the body's defense mechanism against injuries, infections, viruses or bacteria. Usually, inflammation is a temporary and self-healing process, but it also happens that a chronic inflammation develops. Inflammation is a complex reaction involving different chemical signals and cell types.
