Description

technical field [0001] The invention belongs to the technical field of medical testing, and in particular relates to a detection reagent for glycosylated serum albumin and an application thereof. Background technique [0002] Glycated serum albumin (glyecatedalbumin, GA) is a ketamine compound formed by the combination of glucose and albumin in plasma through non-enzymatic glycosylation reaction. The glycosylated serum albumin value can reflect the average blood sugar level of diabetic patients 2-3 weeks before the test, which is consistent with the gold standard of blood sugar monitoring, HbA IC In contrast, GA can reflect the short-term fluctuation of blood sugar, and can more accurately reflect the blood sugar of diabetic patients. Good blood sugar control can effectively delay the occurrence and development of diabetes and chronic complications. Therefore, the determination of glycosylated serum albumin is of great significance in the diagnosis, short-term monitoring a...
