Continuous glucose monitoring (CGM) devices are gaining popularity in the daily monitoring of diabetes, for both doctors and patients. Moreover, they are being used in the scientific research, in which the data analysis is not only a daily average value of blood glucose but also its daily profile changes.


"GlyCulator" tool provides a quick conversion of the parameters of glycemic variability based on CGM report. In current version available variability parameters are: mean, median, SD, %CV, M100, J, MAGE, MODD, CONGA (for 1h, 2h, 4h and 6h time intervals), FD, percentage of hyperglycemia (levels above 7 mmol/L and 10 mmol/L) and hypoglycemia (levels below 3.9 mmol/L) episodes. They are calculated for the first complete two days from imported CGM data set. Additionally, basic variability parameters (mean, SD, median, %CV, M100, J, MAGE, hyperglycemia and hypoglycemia episodes) are calculated for the whole CGM file.
