Definitions for "Hemoglobin A1C"
The HgbA1C measurement assesses glucose control over the past 2-3 months. It is recommended approximately every 3 months in diabetics.
Hemoglobin A1C is a blood test. It measures your average blood glucose level over a set period of time (8 to 12 weeks) leading up to scheduled office visits.
The component of red blood cells that carries oxygen to the body's cells, it also carries sugar through the bloodstream. Because the sugar is attached for the life of the cell, which is about four months, a test of hemoglobin A1C shows the average blood glucose level for that period of time.
