What Are the Normal A1C Levels for the Non-diabetic?

A1C levels are important in controlling diabetes, and non-diabetic people should also watch their A1C levels. Different from urine tests or daily finger sticks, A1C test measures average blood sugar level over the past two to three months, rather than just in the moment. That’s why its results are more accurate and reliable. In fact, our blood sugar level vary wildly depending on the time of the day, activity levels and even hormone changes, and A1C test reflect the general conditions rather than a momentary record.

What can A1C test do?

In other words, your finger stick result may show that you have a high blood sugar level, but if your A1C test tells you that you are non-diabetic, then you are fine. Now, A1C test is widely used to help doctors diagnose prediabetes and monitor your diabetes treatment.

Normal A1C levels for non-diabetic people:

Blood sugar is only one symptom of the diabetes. So far we have cared so much about the dangerous levels and boundaries for the diabetic. Actually, for the non-diabetic, we need to pay attention to the following numbers.

1) A1C (range): 4.5 – 5.8 (used to be 6.0 or even 6.5)

2) Fasting Blood Sugar (range): 60 – 99 (the next 20 points or so are sometimes called “pre-“)

3) +1hour, +2hours and +3hours post meal values: 140, 120, 100, respectively

A1C range

An A1C between 5.7 and 6.4 percent signals prediabetes. And type 2 diabetes is diagnosed when the A1C is over 6.5 percent. For many people with type 2 diabetes, the goal is to lower A1C levels to a healthier percentage.

By the way, after-meal numbers below 180 can be “normal”. This number can vary wildly. Some non-diabetics do indeed reach the 160s after a meal. In fact, the numbers listed above may be pure speculation or averaging of data. A healthy person stands the chance of his/her blood level rushing out of the normal range. If so, you need more tools to calculate your health index.
