Red blood cells circulate in the body for about three months before they die. A Hemoglobin A1c shows an average of how much sugar has been around for the preceding three months. This information is extremely important because research has proven the longer an individual is exposed to elevated blood sugars over an extended period of time, the higher the risk is for developing problems such as Alzheimer’s disease. An elevated hemoglobin A1c is also a threat to eye, nerve and heart health.
Test Preparation For Optimal Results:
If possible, have the lab collected early in the morning or shortly after waking. For comparison purposes, have subsequent labs collected close to the same time.
Disclaimer: A health care provider should evaluate a deviation from normal ranges.
