2021年3月15日 · GMI provides an estimated A1C level based on continuous glucose monitoring data and can avoid some of the limitations of A1C tests. A recent study compared actual A1C levels with GMI to see how the two compared in the real world.

A1c measures average blood glucose over three months, while GMI estimates glucose levels based on continuous glucose monitoring data.

A1C results from blood tests, while GMI is estimated from CGM data. Combining them, for instance, through a a1c estimation calculator, offers a better understanding of blood sugar control.

GMI vs A1C: GMI estimates average glucose from CGM; A1C reflects past 2-3 months. Measurement Methods: GMI uses real-time CGM data; A1C is lab-tested hemoglobin. …

2025年1月4日 · Knowing the difference between GMI and A1C is key to managing your diabetes successfully. GMI stands for glycemic metric index. It is the data from your continuous glucose monitor (CGM). A1C is a laboratory test that measures your average red blood cell glucose over the past 2-3 months.

My most recent lab A1c test was 7.6, but my 90-day CGM report (GMI) said my estimated A1c was 6.9. What’s the difference between the two, how can they be off by so much, and which …

2023年11月25日 · While A1C and GMI results may differ, it is an important comparison to have a bigger conversation about overall diabetes management. If someone has CKD, it is expected that the A1C will be falsely lower than actual glucose averages. GMI would help fill in the gaps created by that limitation.

2024年10月4日 · GMI uses a formula based on the mean glucose level obtained through CGM readings and expresses it as a percentage, similar to HbA1c levels. Specifically, GMI is …

2018年9月17日 · While A1C is well established as an important risk marker for diabetes complications, with the increasing use of continuous glucose monitoring (CGM) to help facilitate safe and effective diabetes management, it is important to understand how CGM metrics, such as mean glucose, and A1C correlate.

Understanding the differences between GMI and A1C is crucial for effectively managing Type 1 Diabetes and tailoring personalized treatment plans. A1C measures average blood glucose levels over 2-3 months based on red blood cell turnover, while GMI can be checked more frequently using CGM data.
