Diagnosing Rheumatoid Arthritis
Rheumatoid arthritis (RA) is an autoimmune disorder that causes inflammation in the joints, leading to pain and stiffness. Diagnosing RA can be challenging, as the symptoms are similar to other conditions. It is important to see your doctor if you experience persistent joint pain and stiffness, as this could be a sign of RA.
Your doctor will take a detailed medical history, including your family history, and perform a physical exam. They may order a series of tests, including blood tests, imaging tests, and joint fluid tests, to diagnose RA.
Blood Tests
Blood tests are used to look for signs of inflammation in the body and to detect certain antibodies, called rheumatoid factor (RF), that are produced by the immune system when it is triggered by RA. The presence of RF is one of the most important factors in diagnosing RA.
Imaging Tests
Imaging tests, such as X-rays, can help your doctor to assess the extent of joint damage, which may be due to RA.
Joint Fluid Tests
Joint fluid tests can help to confirm a diagnosis of RA. A sample of fluid is taken from the affected joint and then tested for signs of inflammation.
Your doctor may also refer you to a rheumatologist, who is an expert in diagnosing and treating RA. They may recommend additional treatments, such as medications and lifestyle changes, to help manage the symptoms of RA.
