Glycated albumin (GA), with a normal range of 11%-17%, can be used mainly to detect short-term blood glucose control and can reflect the average blood glucose level in the past 2-3 weeks. The clinical measurement of glycated albumin is mainly used to make up for the deficiency of glycated hemoglobin and fingertip glucose monitoring. The advantages of fingertip glucose and glycated hemoglobin monitoring are that fingertip glucose can provide accurate fasting and postprandial glucose values, while glycated hemoglobin can reflect the average level of blood glucose in the past 2-3 months, which is an important indicator for diagnosing diabetes and assessing whether the long-term control of blood glucose is up to standard. However, there are shortcomings in that fingertip blood glucose cannot reflect the whole day blood glucose spectrum and the degree and magnitude of blood glucose drift. Because hemoglobin is present in red blood cells, detection is affected by the life span of red blood cells. In contrast, the glycosylation reaction speed of albumin is 4.5 times faster than that of hemoglobin. When blood glucose fluctuates in diabetic patients, glycated albumin changes faster than glycated hemoglobin, which can provide valuable information to patients with fluctuating blood glucose earlier. Moreover, since albumin is not present in red blood cells, it is not affected by iron metabolism and red blood cell lifespan. Therefore, the advantage of glycated albumin is more obvious for patients who have diabetes and combined with pregnancy, anemia and kidney failure.
