HbA1c has been the gold standard for assessing glycemic control for decades, but it is not perfect. It provides an average, not a picture of variability. It does not capture hypoglycemia or postprandial spikes. And in some patients, conditions such as anemia or hemoglobin variants make HbA1c unreliable. These limitations have driven interest in complementary and alternative approaches, including continuous glucose monitoring, which provides real-time data on glucose fluctuations throughout the day and night.

Continuous glucose monitoring has grown rapidly, particularly among people with type 1 diabetes and those with type 2 diabetes on insulin. It provides metrics such as time in range, glucose variability, and time in hypoglycemia, which offer a more nuanced view of glycemic control than HbA1c alone. Some guidelines now recommend using these metrics alongside HbA1c, and in some cases, they may become primary. This evolution does not eliminate the need for HbA1c, which remains valuable for diagnosis and long-term assessment, but it changes how it is used. The HbA1c Market is adapting to this landscape, with continued demand for reliable laboratory and point-of-care testing.

Other approaches are also emerging. Fructosamine and glycated albumin provide shorter-term measures of glycemic control, useful when HbA1c is unreliable. Genetic and biomarker research may identify new ways to assess diabetes risk and control. As technology advances, the future of diabetes monitoring will likely involve a combination of tools tailored to individual needs. HbA1c will remain a cornerstone, but it will be part of a richer, more personalized picture of glycemic health.

People Also Ask

Is HbA1c still the best measure of diabetes control?
HbA1c remains essential for diagnosis and long-term assessment, but continuous glucose monitoring provides additional information on variability and time in range.

What is time in range in diabetes?
Time in range is the percentage of time glucose stays within a target range, measured by continuous glucose monitoring, offering a more detailed view of glycemic control than averages alone.
