## GRI Calculator Description
GRI Calculator - Glycemia Risk Index - For Healthcare Professionals

Calculate the Glycemia Risk Index (GRI) quickly and accurately with this professional tool designed for clinicians managing patients with diabetes.

Overview

The GRI Calculator enables healthcare providers to assess glycemic control quality by analyzing continuous glucose monitoring (CGM) data. Simply input the percentage of time spent in VLow, Low, VHigh, and High glucose ranges from a standard 14-day Ambulatory Glucose Profile (AGP) report.

Key Features

Multi-Point Plotting - Plot multiple patients or multiple points over time
Visual Risk Assessment - View color-coded risk zones from A (minimal risk) to E (severe risk)
Interactive Plot Visualization - See the GRI plotted on a clear, easy-to-read graph
Evidence-Based - Built on peer-reviewed research published in the Journal of Diabetes Science and Technology
Reference Ranges - Quick access to glucose range definitions for VLow, Low, VHigh, and High
Educational Resources - Comprehensive reference section with links to relevant scientific articles

Professional Use

This calculator is intended for use by healthcare professionals as part of comprehensive diabetes management. GRI values help clinicians quickly identify patients who may need treatment adjustments, providing a standardized metric for assessing glycemic variability and risk.

Privacy First

No personal or patient data is collected, stored, or transmitted. All calculations are performed locally on your device.
