Time in Range Calculator — Diabetes Glucose Monitoring Analysis

Time in Range Calculator

Calculate your Time in Range percentage from glucose readings. Analyze diabetes management and get personalized insights for better glycemic control.

Step 1: Glucose Readings

14

More readings provide more accurate Time in Range calculation. CGM data with 14+ days is recommended.

About Glucose Readings

Time in Range (TIR) is the percentage of time spent in the target glucose range (usually 70-180 mg/dL). Higher TIR indicates better diabetes management.

Clinical Targets

For most people with diabetes, the goal is >70% Time in Range (70-180 mg/dL), <4% Time Below Range (<70 mg/dL), and <25% Time Above Range (>180 mg/dL).

Personalized Recommendations

Based on your Time in Range of 68%

Consider reviewing your mealtime insulin doses or carbohydrate counting accuracy. Monitor post-meal glucose spikes and consider adjusting pre-meal insulin timing. Discuss these results with your healthcare team.
