There are 3 ways to be diagnosed with diabetes.

1. Two fasting blood glucose readings over 126
2. A fail on the oral glucose tolerance test which is scoring 200+ on it.
3. A random reading of 200+ that is accompanied by diabetic symptoms.

Currently A1c is not one of the diagnostic criteria and I don't think it should be, at least as a single test. It doesn't test blood sugar like the others do and is not solely based on blood sugar. Sounds like he was diagnosed via option 2. Personally I think a lot more care needs to be taken in diagnosis and a battery of tests done. That way you get the diagnosis but also find where the specific problems lie and cab target therapy much more effectively. Putting somebody who has very little insulin production on the same starting treatment as somebody who is highly insulin resistant doesn't make sense to me but that's what happens now.

They found me with #3. A reading over 450. Drinking like a racehose, expelling like a racehorse. Blurry vision. Headaches. Triage nurse did a simple meter reading and informed me, "You have diabetes" To someone who didnt know what that was.

A day or so ago, I posted a news article concerning this subject on the site in the "News & Articles" section.

Here is a quote from the article:

*"This shift on the use of HbA1c for diagnosis stands to legitimize the method that is already commonly used by many primary care physicians, said Dr. Mayer B. Davidson, an endocrinologist at Charles R. Drew University of Medicine and Science in Los Angeles and professor of medicine at the University of California, Los Angeles. He applauded the decision, noting that “HbA1c is a more valid way to look at what is going on with glucose,” compared with glycemia levels."*

If you would like to read the article, here is the link. Hope this helps.

The Glucose Tolerance Test is usually ordered as a 2 hour test. They draw your blood and test your glucose then have you drink the liquid glucose, 2 hours later they do a blood draw test again to see if your blood glucose went up, down, remained the same, etc. This number usually looks like what you would see on your testing meter…such as a 168.
An A1C test is a blood draw test that tests the glucose range over the past 3 months usually, it gives a percentage as the answer such as 6.6% rather than a whole number like a GTT (glucose tolerance test) does.
Normally a GTT is done to see if you are diabetic and an A1C is done after you are diagnosed to see how whatever treatment plan you are on is working.
They aren't always done in this order but thats the difference between them in a very shortcut answer lol

I agree with what Robin just told you. They found out he was a diabetic with the gluclose toleranece test. An A1c test is a test I get every 3 mons to give my Endos a sign if I am (cheating) I call it or not. (LOL)…Debe
