Diagnosing Prediabetes or Diabetes A normal A1C level is below 5.7%, a level of 5.7% to 6.4% indicates prediabetes, and a level of 6.5% or more indicates diabetes. Within the 5.7% to 6.4% prediabetes range, the higher your A1C, the greater your risk is for developing type 2 diabetes.
Is an A1C of 5 too low?
However, low or extremely low HbA1c (<5.0% or <4.0%) may occur in apparently healthy individuals. When this occurs, it is an independent risk factor associated with liver diseases, hospitalization, and all-cause mortality.
Is 5 high for a blood sugar level?
A fasting blood sugar level less than 100 mg/dL (5.6 mmol/L) is normal. A fasting blood sugar level from 100 to 125 mg/dL (5.6 to 6.9 mmol/L) is considered prediabetes. If it's 126 mg/dL (7 mmol/L) or higher on two separate tests, you have diabetes.
Is an A1c of 5.1 okay?
An A1c level of less than 5.0% means a 48% lower risk of diabetes and about the same risk of heart disease. An A1c level of 5.5% to 6.0% means an 86% higher risk of diabetes and a 23% higher risk of heart disease.Mar 3, 2010
