You most likely do have rheumatoid arthritis. In 2010, new diagnostic criteria were established. A point system is used; with the points awarded for which joints are affected, elevated and ESR, positive rheumatoid factor and Anti-CCP. People suspected of having RA do not have to have points in all areas. By using this system, we believe we can diagnose and thereby treat people earlier in their disease than previously.
An important note to this system ; anyone displaying a joint erosion on x-ray, will automatically receive the RA diagnosis regardless of the number of points achieved.
