Test Description

Why get tested?

The RA factor test is used for diagnosing autoimmune disorders such as arthritis. Rheumatoid arthritis is an inflammatory and autoimmune disorder, that causes the immune system to mistakenly attack the healthy cells in the body. This results in inflammation or painful swelling in the affected regions of the body. Mainly RA attacks the joints. Commonly, RA attacks many joints at the same time. Moreover, it may also affect the knees, wrists, eyes, heart, lungs, and hands. It causes inflammation in the joint’s lining, which damages the joint’s tissue. The damaged tissue causes chronic or long-lasting pain, deformity, and lack of balance or unsteadiness. 

What is being tested?

An RA factor test determines the number of rheumatoid factors in the blood. Rheumatoid arthritis (RA) factors are proteins synthesized by the immune system. Generally, the immune system stops disease-causing agents such as bacteria and viruses, however, a disorder of the immune system can also make it attack healthy tissues and organs in the body. The most common reasons for high quantities of RA factor in blood specimens are autoimmune disorders, especially rheumatoid arthritis.
