About This Tool
This online MDRD GFR calculator aids healthcare professionals and patients in estimating kidney function through the Modified Diet in Renal Disease (MDRD) formula. It simplifies complex calculations by accepting essential patient data such as age, serum creatinine, sex, and ethnicity, then automatically computing the estimated glomerular filtration rate. Accurate GFR measurement is vital for diagnosing, monitoring, and managing chronic kidney disease (CKD).
The tool features a clear, responsive form with input validation to ensure correct data entry. Results are displayed immediately after calculation, including GFR value (mL/min/1.73 m²) and interpretative guidance (normal, decreased, or severely decreased kidney function). It supports multiple units where applicable and offers options for data export or sharing. The interface employs a modern, minimal design with accessible colors and fonts, ensuring usability across devices and for users with disabilities.
Ideal for healthcare settings, research, and personal health tracking, this tool promotes early detection and ongoing management of renal health. It does not replace professional medical advice but offers a valuable aid for initial assessment and monitoring.
