How is rheumatoid arthritis diagnosed?

The diagnosis of rheumatoid arthritis is based on a combination of symptoms, clinical examination, and laboratory tests. The doctor assesses the patient’s symptoms and conducts a physical examination, paying special attention to swelling and tenderness in the joints. Laboratory tests measure inflammation values such as CRP and rheumatoid factor, as well as other specific antibodies like CCP antibodies. The diagnosis may also require imaging studies, such as X-rays, ultrasound, or MRI, which help assess the condition of the joints and any possible damage.
