Disease Activity Score-28 (DAS-28) for Rheumatoid Arthritis
The DAS-28 helps doctors assess rheumatoid arthritis by checking 28 joints for swelling and pain. It combines physical exams with blood tests to track disease activity and guide treatment.

What is Disease Activity Score-28 (DAS-28)
The Disease Activity Score-28 (DAS-28) is a key tool for measuring rheumatoid arthritis activity. It helps doctors track patient progress reliably. This assessment focuses on twenty-eight specific joints in the body. It combines physical exams with blood test results to provide a clear picture of inflammation levels. Clinicians count swollen and tender joints, mostly in the hands, arms, and knees. Patients also rate their general health on a visual scale. These factors mix with lab markers like ESR or CRP to calculate a score indicating current disease status. Using the DAS-28 is standard practice for rheumatologists worldwide. It allows for consistent monitoring over time, helping teams decide if a treatment plan needs changing. Whether aiming for remission or low activity, this score guides therapy choices and improves long-term joint health outcomes.
The Disease Activity Score 28 can be scored using complex formulas based on four key health markers. First, you count tender and swollen joints out of 28 specific spots. Next, combine these counts with blood test results like ESR or CRP and the patient's global assessment of health on a 0 to 100 scale. Doctors plug these numbers into a special maths formula to get a final result between 0 and 9.4. A score under 2.6 suggests remission, while anything over 5.1 points to high disease activity, helping clinicians decide if current treatments are working well.
