What Exactly Does A Normal A1C Tell You?

What Exactly Does A Normal A1C Tell You?

The A1C test has become the “gold standard” in the diagnosis/treatment of Diabetes but that wasn’t always the case.

The idea for the test was discovered in the 1950’s.

The test was first produced in 1979.

In 1983 a study (DCCT – Diabetes Control and Complications Trial) was undertaken to investigate it’s reliability and effectiveness.

In 1993 (concluded 10 year study) it was determined that A1C was “viable” with limitations.

It wasn’t until 2009 that “guidelines” for using A1C were written… read more

I agree with you, the A1C is an average but does not give the actual readings. I am now using a Constant Glucose Monitor (CGM) that takes readings every five minutes. It graphs my results to as long as 90 days and my endocrinologist likes to check out my CGM results and the A1C results. I still use the finger poking testing once a day to calibrate my CGM. The CGM is good in identifying food causing higher blood glucose levels. It also identifies food that keep your blood glucose levels lower. I am lucky that my benefit plan is paying all my CGM costs.

Ohh for me poking myself 3-4 times a day (sometimes more) is frusterating because I know those machines are not 100% accurate! And that right there is super frusterating. Because it adds to my voodoo doll feeling!

Last A1c check I was 5.8 before this because of hypos I was 5,2

I often wonder "What is normal" because normal is the last thing I feel like.
I am so thankful for all of the things that you bring up Graham because it gives me things to talk to the doctor about.
I need to have her hand me over to an Endocrinologist and keep forgetting to tell her this.. Thanks always for all of your help. you are most certainly a blessing in my world!
