hemoglobínA1c

Hemoglobin A1c, often abbreviated as HbA1c or simply A1c, is a type of glycated hemoglobin. It is formed when glucose in the bloodstream binds to hemoglobin, a protein in red blood cells responsible for carrying oxygen. The rate at which glucose binds to hemoglobin is proportional to the blood glucose concentration. Therefore, the A1c level provides an average of a person's blood glucose levels over the preceding two to three months, which is the lifespan of red blood cells.

The A1c test is a common diagnostic tool used to monitor long-term blood sugar control in individuals with diabetes mellitus. It helps healthcare providers assess the effectiveness of diabetes management strategies and identify the risk of developing diabetes complications, such as heart disease, kidney disease, and nerve damage. A higher A1c value indicates poorer blood glucose control over time. Conversely, a lower A1c value suggests better control.

Typical A1c target levels vary for individuals, but generally, a level below 5.7% is considered normal. Levels between 5.7% and 6.4% suggest prediabetes, and a level of 6.5% or higher on two separate tests indicates diabetes. For individuals diagnosed with diabetes, treatment goals are often set at an A1c below 7% to reduce the risk of complications. Regular monitoring of A1c levels is crucial for managing diabetes effectively and maintaining overall health.
