Rheumatoid factor test is done in the following situations:
A rheumatoid factor (RF) quantitative test is used for detecting the levels of rheumatoid factor (RF) present in your blood. RF is an autoantibody made by the immune system. It targets the body tissues by sensing them as foreign tissues. The presence of RF in the blood signifies that the body is undertaking some autoinflammatory and autoimmune activity.
Rheumatoid arthritis is a chronic inflammatory disorder that can progress either gradually or rapidly. It leads to stiffness, swelling, pain, and changes in our joints. Though it can occur at any age, people above the age of 40 are more prone to it.
Moreover, women are more at risk for developing rheumatoid arthritis as compared to men. Joint disability can also occur if a proper treatment is not received for the disease.
There are no side effects associated with the rheumatoid factor test. However, you may feel a slight pain in the area from where the blood would be withdrawn. This can last for a few days.
