ARTICLE HIGHLIGHTS
Research background

Abnormal glucose metabolism in highland populations is an important health concern in our society today.

Research motivation

Identifying highly accurate blood glucose monitoring methods for use in high-altitude populations is an urgent need.

Research objectives

To evaluate the accuracy of the FreeStyle Libre FGM system in highland populations.

Research methods

A total of 66 patients with type 2 diabetes (T2D) were enrolled in this observational analysis. General information and blood glucose data were statistically analyzed.

Research results

The accuracy of the FreeStyle Libre FGM system in patients with T2D who recently migrated from highlands to plains met national and international standards when finger blood glucose levels measured using the enzyme electrode method were used as the standard.

Research conclusions

The FreeStyle Libre FGM system complements continuous glucose monitoring in highland populations.

Research perspectives

Based on the insights gained in this study, we aim to conduct an extended future study on the difference in the mean absolute relative difference values of FGM between patients with normal and elevated hemoglobin and hematocrit levels.
