Rheumatology & Autoimmune Clinical Calculators
Rheumatology requires highly objective, standardized measurement of subjective symptoms and multi-system disease activity to properly guide immunosuppressive and biologic therapies. The MedCalc Rheumatology Hub provides rheumatologists, immunologists, and internists with 100% offline, zero-latency access to the most vital disease activity scores and diagnostic criteria.
From calculating standard RA indices like the DAS28, CDAI, and SDAI, to quantifying irreversible organ damage in lupus patients via the SLICC/ACR index, these tools eliminate clinical ambiguity at the point of care. All scoring systems and classification criteria are strictly aligned with guidelines from the American College of Rheumatology (ACR) and the European Alliance of Associations for Rheumatology (EULAR).
