How good is my hba1c

[Lawrencepa]

So I haven't been tested in a few months so I can only hope my blood sugar has improved. But I'm just wondering where on the scale my old results would put me. My hba1c is 32 which from what I've read is good. But my fasting blood sugar was 5.6 which isn't so good. I was diagnosed with prediabetes with these results does that sound accurate? Am I only very slightly prediabetic? I did do a GTT but I don't have my results to hand unfortunately. And as far as I'm aware your hba1c is your average blood glucose over 3 months? Correct me if I'm wrong

Numbers like those suggest you are not diabetic at all. I find that fasting tests can be a bit unreliable for a number of reasons so I shall go on your Hba1c. 42 to 48 is pre-diabetic so you don't even qualify.

I still recommend eating right and the odd bit of exercise so that you don't end up like the rest of us.

I find my fasting number is at 5.4 to 5.6 if I had a lot of protein the evening before especially beef otherwise it is around 5.0 so I wouldn't worry about the 5.6 . Well done on a great set of numbers

My GTT was 8.8 is that not considered bad then? It's in the prediabetes range isn't it, also my blood sugar fasting level hasn't seem to have gone down since I started this diet. Should it have by now? It's been 3 months. Or as you say are fasting sugar levels meaningless?

Fasting levels are not entirely meaningless but even the medical profession doesn't rely on them for diagnosis any more and the Hba1c is used instead. Fasting levels can be affected by what you ate the evening before, meter inaccuracy, liver dumps and what time the test was done in relation to a liver dump. If it is a home test then one of the biggest problems is likely to be a meter reading high since many of them do.

An OGTT is useful but you would need a reading over 11 to be be considered diabetic and 8.8 would only be a tad high for a non diabetic. Also the reading before beginning would be taken into account.

The most useful reading is the Hba1c because although it has problems of its own it nevertheless gives the best overview of what is going on and the pre-diabetic range is 42-48. It is said that it is an average of your blood sugar levels for the last three months but research has shown that everyone is different. No surprise there then. You don't get diagnosed as diabetic until the reading is higher than 48.

If ever you have any risk of diabetes then I would say you have caught it very early indeed.

I would imagine you were diagnosed as pre-diabetic because your fasting test and the OGTT at 2 hours put you in that range. The HbA1c was 100% non-diabetic and normal. So 2 out of the 3 possible diagnostic tests came back with pre-diabetes (impaired glucose tolerance)

What should the OGTT results be?
People without diabetes

• Fasting value (before test): under 6 mmol/L
• At 2 hours: under 7.8 mmol/L

People with impaired glucose tolerance (IGT)

• Fasting value (before test): 6.0 to 7.0 mmol/L
• At 2 hours: 7.9 to 11.0 mmol/L

Diabetic levels

• Fasting value (before test): over 7.0 mmol/L
• At 2 hours: over 11.0 mmol/L

Did you have at least 150g of carbs a day for 3 days before your GTT? If not, it is not reliable.

For me fasting only lower's with strict control for several months and it is the first to rise with an off plan meal.

Your HBA1C is fantastic, are you still doing keto for weight loss?
