Rheumatoid arthritis is a chronic autoimmune disease that affects the joints and causes pain, swelling, and stiffness. Detecting it early is crucial to limit damage and maintain a good quality of life. Below, we will tell you which are those key tests that can help you rule out rheumatoid arthritis.
The first step in diagnosing rheumatoid arthritis is through a blood test that evaluates certain markers in the body, including:
Rheumatoid factor is a protein produced by the immune system that is characterized by attacking healthy tissues. About 80% of people with rheumatoid arthritis have a high level of this factor in their blood.
Anti-CCP antibodies are specific to rheumatoid arthritis and are rarely found in other diseases. In this sense, its presence may indicate a more severe course of the disease.
These two tests measure the amount of inflammation in the body. Elevated levels are a clear indication of the presence of an inflammatory disease such as rheumatoid arthritis.
Antinuclear antibodies are common in many autoimmune diseases, including rheumatoid arthritis. A positive result could help confirm the diagnosis.
Once the blood tests are completed, the specialist may suggest imaging tests to get a clearer view of the condition of the joints.
X-rays may show changes characteristic of rheumatoid arthritis, such as bone erosions and reduced joint space.
These imaging techniques can detect inflammation and joint damage that are not visible on conventional X-rays.
There are other tests that can help confirm the diagnosis of rheumatoid arthritis. Among them we can mention:
Synovial fluid is a fluid found in the joints and acts as a lubricant, reducing friction between cartilage and other tissues in the joints; thus allowing a smooth and cushioned movement. Occasionally, it may be examined for inflammation and other signs of rheumatoid arthritis.
These tests are important for monitoring the patient’s overall health and for determining the suitability of certain medications used in the treatment of rheumatoid arthritis.
Remember that rheumatoid arthritis medications can affect liver and kidney function due to their metabolism and elimination. Some drugs can cause liver or kidney toxicity, while others require regular monitoring of liver and kidney function to prevent adverse effects.
Diagnosing rheumatoid arthritis can be a complex process that requires a series of tests. However, early diagnosis is imperative to slow the progression of the disease and prevent as much damage as possible.
