Many individuals with rheumatoid arthritis (RA) face challenges in obtaining a timely diagnosis. Rheumatoid arthritis is a complex autoimmune condition characterized by symptoms like joint swelling, redness, warmth, and muscle strength changes. A doctor will typically conduct a physical examination to assess these symptoms, alongside a series of blood tests.
Key blood tests used in diagnosing RA include the Erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and a Full blood count (CBC). Each of these tests can provide crucial information about the inflammatory processes in the body, which are indicative of RA.
It’s important to note that no single blood test or physical finding can conclusively confirm RA. Symptoms such as loss of appetite, weight loss, weakness, dry eyes and mouth, and the presence of firm lumps beneath the skin are also considered. However, these symptoms can be due to conditions other than RA if they persist for less than six weeks. The longer a patient experiences these symptoms, the more likely they are to be attributed to RA.
Rheumatoid factor (RF), an autoantibody often found in people with RA and other autoimmune diseases, plays a significant role in diagnosis. The association between RF and RA has been recognized for almost a century.
The global impact of rheumatoid arthritis is significant, affecting people of all ages and backgrounds. As an autoimmune disease, it presents a pervasive challenge in the medical community.
