Disease Activity Score

The Disease Activity Score (DAS) is a measurement used by doctors to assess how active or severe rheumatoid arthritis is in a patient. It combines evaluations of joint swelling and tenderness, along with blood tests for inflammation and sometimes overall health. This score helps doctors understand how well a treatment is working and guides them in adjusting therapies. A lower DAS indicates less disease activity, meaning better control, while a higher score suggests more active disease requiring attention. It’s a useful tool for tracking disease progress over time and making informed treatment decisions.
