## What is CKD Staging & eGFR Calculator?

CKD Staging & eGFR Calculator – Kidney Risk

Understand kidney-related lab values and risk categories in seconds.

Kidney Risk Calculator helps you calculate estimated Glomerular Filtration Rate (eGFR) using established clinical equations and visualize chronic kidney disease risk categories based on KDIGO guidelines. The app supports both CKD-EPI 2021 (revised) and CKD-EPI 2009 (original) formulas, adjusts for Body Surface Area (BSA), and displays KDIGO risk using the standard heatmap model.

Designed as an educational and reference tool for patients, caregivers, students, and healthcare professionals.

This app is intended for educational and informational use only and is not designed to diagnose, treat, or monitor medical conditions.

One-time purchase. No subscriptions. No ads. No tracking.

Key Features

• eGFR Calculator (CKD-EPI 2021 + 2009)
Estimate eGFR using both CKD-EPI equations. View results as normalized (per 1.73 m²) or absolute values adjusted for actual body surface area.

• Body Surface Area (BSA) Calculator
Estimate BSA using the Mosteller formula and understand how body size influences eGFR interpretation.

• KDIGO Risk Matrix (CKD Staging Heatmap)
Visualize chronic kidney disease risk categories using the KDIGO GFR/UACR matrix for clear interpretation of results.

• Physique Adjustment Warnings
Provides context where body composition may influence creatinine-based eGFR interpretation.

• PDF Summary Export
Generate a one-page summary for personal reference or discussion with a healthcare provider.

Based on Trusted Clinical Standards

• CKD-EPI 2021 Revised Equation
• CKD-EPI 2009 Original Equation
