Rheumatoid arthritis diagnostic criteria information!

I would like to share in detail the diagnostic criteria for rheumatoid arthritis.

Rheumatoid arthritis is an autoimmune disease.
It is a chronic disease in which the immune system attacks its own joints, causing inflammation.

As a result, pain, swelling, and stiffness occur.
In the long term, it can lead to joint damage and deformity.

To obtain accurate diagnostic criteria for rheumatoid arthritis, various factors must be considered.
These are the main diagnostic criteria for rheumatoid arthritis.

1. Joint symptoms: Diagnostic criteria for rheumatoid arthritis
   
   

   • Persistent inflammation: Swelling and inflammation persist for at least one joint for more than 6 weeks. This does not indicate a simple temporary inflammation but a chronic inflammatory condition.
     
     
   • Involvement of small joints: Usually begins in small joints (wrist, fingers, etc.) and is especially common in the hands and wrist joints.
     
     
   • Symmetry: Symmetrical arthritis is characteristic. For example, if a specific joint in the left hand swells, the same joint in the right hand often swells as well.
     

2. Blood test: Diagnostic criteria for rheumatoid arthritis
   
   

• Rheumatoid factor (RF): An antibody that tests positive in many RA patients. However, it can also be positive in other diseases that are not RA, so it is not used alone for diagnosis.
  
  
• Anti-CCP antibodies: They have high specificity and play an important role in the diagnosis of RA. When anti-CCP antibodies are positive, the reliability of RA diagnosis increases.
•  
• Inflammation markers: Elevated levels of **C-reactive protein (CRP)** and **erythrocyte sedimentation rate (ESR)** indicate the level of inflammation. These markers reflect the degree of inflammation within the body.
