From my own experience, they usually check for Fasting Blood Sugar, then sometimes a Post-Prandial (after food) test, and often an HbA1c. But I'm not a doctor, so this is just what I went through. Your doctor will know best.

If you go to a good hospital, the doctors will clearly tell you. But generally, they do Fasting Blood Sugar, Post-Prandial Blood Sugar (PPBS), and the HbA1c test. Just ask your doctor about which ones are right for you.

Yaar, they usually do a Fasting Blood Sugar test, then a Post-Prandial, and the most important one, actually, is the HbA1c. That gives you a 3-month average. Better to get all three if doc says so.

As someone managing thyroid, I know regular check-ups are essential. For diabetes, the key tests are Fasting Blood Sugar, Post-Prandial (after meal) Blood Sugar, and HbA1c. Make sure to get these done periodically as advised by your doctor.

My doctor explained that for diabetes, they use Fasting Plasma Glucose (FPG), a Two-hour Plasma Glucose (Oral Glucose Tolerance Test), and Glycated Hemoglobin (HbA1c). The HbA1c is particularly good because it gives an average over a few months, not just a snapshot.

I'm not sure, but is it the blood sugar test? Like, when you don't eat anything? And then something after eating? Do they always do both, or just one? Sorry, just trying to understand.

For diabetes diagnosis, the main tests are Fasting Blood Glucose, Oral Glucose Tolerance Test (OGTT), and HbA1c. I log all my sugar readings in my health app, but for actual diagnosis, these blood tests are crucial. Talk to your doc for precise tests.

To check for diabetes, they look at Fasting Blood Sugar, Post-Prandial (after food) Sugar, and most importantly, the HbA1c test, which gives a 3-month average. Always be mindful of your diet and sugar intake, it makes a huge difference.

I totally get that feeling of needing to know. For diabetes, they typically check Fasting Blood Sugar, Post-Prandial Blood Sugar, and HbA1c. Don't hesitate to ask your doctor any questions you have; it's your health, after all.

I was pre-diabetic recently and got diagnosed through a Fasting Blood Sugar test and an HbA1c. These are the main ones they use. Luckily, I was able to manage it with lifestyle changes. Get yours checked early!

Back in my day, we didn't have as many tests, but now they do Fasting Blood Sugar, Post-Prandial, and the HbA1c for diabetes. It's good they have these tests. Don't be afraid to get checked, it helps to manage things better in the long run.
