Prueba de hemoglobina glucosilada (hemoglobina A1c)


Prueba de hemoglobina glucosilada (hemoglobina A1c)

(Glycosylated Hemoglobin Test (Hemoglobin A1c))

La hemoglobina es una sustancia que está dentro de los glóbulos rojos y que transporta oxígeno a las células del cuerpo. Por lo general, las moléculas de glucosa (un tipo de azúcar) de la sangre se adhieren a las de hemoglobina: esto significa que la hemoglobina se ha glucosilado (esta hemoglobina también se llama A1c o HbA1c). A medida que aumenta el nivel de azúcar en sangre de una persona, una mayor proporción de su hemoglobina se glucosila. La glucosa queda adherida a la hemoglobina durante toda la vida del glóbulo rojo, o de 2 a 3 meses.

Un análisis de sangre puede medir la cantidad de hemoglobina glucosilada en la sangre. La prueba de hemoglobina glucosilada muestra el nivel medio de glucosa en sangre que tenía la persona 2 ó 3 meses antes de someterse a la prueba. Esto puede ayudar a determinar si se está controlando bien la diabetes.
