About this calculator
The CGM TIR Calculator is a useful tool for patients with diabetes who use continuous glucose monitoring (CGM). It helps calculate the percentage of glucose readings within the desired range (between 70 and 180 mg/dL), which is crucial for maintaining disease control.
The TIR is an important measure to evaluate treatment effectiveness and adjust insulin doses, if necessary. With this calculator, you can calculate your TIR and discuss the results with your doctor to develop a personalized treatment plan.
Remember that TIR is only one tool for managing diabetes. It's essential to consult a healthcare professional for personalized guidance and adjust treatment according to your individual needs.
It's essential to remember that glucose readings should be taken at specific times of the day, such as before each meal and before bedtime. Additionally, it's critical to monitor glucose levels regularly to ensure they're within the desired range.
