Standard glucose tests only measure blood sugar levels at the time the sample is collected. This HbA1c (hemoglobin A1c) test measures your average blood sugar level over an extended period (8-12 weeks) and is a useful tool for screening for prediabetes and diabetes.
Knowing your average blood sugar levels serves as a critical indicator of your health. Consistently elevated blood sugar levels often indicate prediabetes and diabetes: a serious disease that can ultimately affect the health and function of other parts of the body including your nervous system, cardiovascular system, eyes and kidneys.
Preparation: No special preparation needed.
Measures the average amount of glucose in your blood over an extended period (typically 8-12 weeks).
More than 100 million Americans have diabetes or prediabetes, and 8.5 million aren’t aware they have diabetes.
It is estimated that 8 in 10 people do not realize they have prediabetes which can cause complications that build up over time. Prediabetes, often reversible with healthy lifestyle changes, can cause health complications if left untreated or unmanaged.1
Without taking action, many people with prediabetes go on to develop Type 2 diabetes and other chronic conditions or diseases.
Studies show that moderate weight loss and exercise can delay, or even prevent the development of Type 2 diabetes among high-risk adults.
The American Diabetes Association recommends prediabetes and Type 2 diabetes screening for anyone 35 years of age or older.2,3

A1c measures the average amount of glucose in your blood over an extended period (typically 8-12 weeks), providing better insight of whether your blood sugar levels have been on track over the last few months.
