Hemoglobin is a protein carried by red blood cells or red blood cells. The sugar from the blood binds to hemoglobin to form hemoglobin A1 (glycosylated).
If the blood contains more sugar and glycated hemoglobin increases on all that remains increased during 120 days. Therefore the measurement of glycated hemoglobin reflects the ups and downs of blood sugar in the last eight weeks or more.

Hemoglobin A1 is an average level of sugar in recent months, while a test for blood sugar (glucose) only tells you the status of their diabetes control at some point.
