General Information About the Test
Test Process and Preparation
In healthy individuals, this value is generally below 5.7%. A value between 5.7% and 6.4% indicates you are at risk for Hidden Sugar (Prediabetes). A value of 6.5% and above results in a diagnosis of Diabetes.
Fasting blood sugar shows the sugar level at the exact moment the blood is drawn and can fluctuate instantly depending on what was eaten or drunk the day before. HbA1c, on the other hand, acts like a patient's "report card," showing how faithfully the patient has adhered to their diet and medications over the past 3 months.
No. Since HbA1c shows a 3-month average, whether you are fasting or full at the time of the test absolutely does not change the result. Blood can be drawn at any time of the day.
Because the lifespan of red blood cells and blood volume change during pregnancy, the HbA1c test alone may be insufficient to diagnose gestational diabetes. For this reason, the Oral Glucose Tolerance Test (OGTT) is the gold standard diagnostic method for pregnant women.
