@A DiabetesTeam Member I'm not exactly clear what it is you are asking

The "AI answer Bot" actually did a great job of identifying the OGTT, which is a seldom used test that has existed for a long time (long before A1C came along) but traditionally (before A1C which has only been used for the past 25'ish years), your "level of control" (or lack of) was gauged simply by a Fasting Blood Glucose Test

The OGTT is a 3 hour adventure at a Lab

You fast for 8 or 12 hours

They take a blood sample to establish base sugar levels then you do a 75 or 100 gram equivalent "shooter" of Glucose and find a comfortable chair

At hour 1, 2 and often 3 they take another blood sample (and you could do a couple more an hour a part)

Then the comparison between the readings (one hour apart) will show:

How fast the glucose got in your system (hour 1) and how high you are peaking out (you "should" be peaking at hour 1)

Where you are at "hour 2" - an un-impaired individual's (system) should have spotted the peak, released insulin from the pancreas to (attack) the sugar and get it fed to the cells, turning the leftover's into body fat, and returned you blood sugar level to "below 7.8 mmols or 140 points"

If you are higher than that, that determines "how messed up your system is" compared to baseline

So then it is checked again at hour 3 to (layman's explanation - I'm not a Doc/Lab Tech etc) to see "how long you are still damaging your system and how badly"

If this test is coupled with a "Fasting C-Peptide Test" (can use the same blood as the very first blood sample) then not only can they figure out how "broken" your system is but also your level of insulin "resistance" - everything an Endocrinologist would need to see exactly how your system is working, how impaired it is, how bad your resistance is to using insulin is and what course of treatment is best

However, for about 80% of Type 2's, the very simple - don't have to fast, can take it anytime, A1C test is "good enough" despite it giving very little diagnostic information

- After two hours, another blood sample is taken to measure how the blood glucose level has risen in response to the drink.

- Results Interpretation:
- Less than 100 mg/dL after an eight-hour fast is considered normal.
- 100 to 125 mg/dL indicates prediabetes.
- 126 mg/dL or higher indicates diabetes.

To access this test, you should consult with your doctor, who can schedule and perform the OGTT.
