DAS28-CRP (Disease Activity Score 28 with CRP) - Scientific Formula
Rheumatology Equation
Standard Calibration Equation:
DAS28-CRP = 0.56 × √(TJC28) + 0.28 × √(SJC28) + 0.36 × ln(CRP + 1) + 0.014 × GH + 0.96
Accuracy Bounds & Limits:
While mathematical calculators evaluate demographic models, extreme variance (hyperthyroidism, dialysis cases, muscular bodybuilders, pregnancy) can trigger output errors. Weight and clearance assessments must follow separate personalized titration grids.
