DAS28-CRP — Rheumatoid Arthritis Disease Activity Score

Calculate the Disease Activity Score 28 using CRP (DAS28-CRP) to quantify rheumatoid arthritis disease activity, preferred in patients with chronically elevated ESR due to non-inflammatory causes.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.
