Glycated hemoglobin is an indicator for diabetic patients to test their blood glucose. The value of glycated hemoglobin is not easily affected by factors such as eating, hypoglycemic drugs, etc. Factors affecting glycated hemoglobin include age, medication, hyperlipidemia, and so on. 1. Age: Age is an independent factor affecting the level of glycosylated hemoglobin, and the normal range of glycosylated hemoglobin can increase with age. 2. Drugs: Vitamin C, vitamin E and other drugs can inhibit glycosylation of glycated hemoglobin, making the measured level of glycated hemoglobin low. High doses of acetylsalicylate, erythropoietin, ribavirin and other drugs can shorten the life span of red blood cells, which can also lead to lower test results. 3. Hyperlipidemia: Glycated hemoglobin test values of patients with hyperlipidemia will be high to a certain extent. The temperature and ionic strength of reagents used in the laboratory to test glycated hemoglobin may affect glycated hemoglobin. Consult your healthcare professional for Glycated Hemoglobin testing and analysis of results.
