how is a Glycated hemoglobin (A1C) test performed
The A1C test is a blood test used to measure the average level of glucose in the blood over the last two to three months, and is used as a means of checking how well blood sugar levels are being controlled for a person with diabetes.. The particular type of hemoglobin that glucose attaches to is hemoglobin A, and the combined result is call glycated hemoglobin. As blood glucose levels rise, more glycated hemoglobin forms, and it persists for the lifespan of red blood cells, about four months.
