I'm not on any diabetic meds and my niece is a diabetic and she is on meds. She asked me if I had a test where you drink a liquid. Shouldn't the doctor have ordered it? My niece seems to think so. Maybe I just had a lot of carbs the day before I had the blood test?

I’m assuming your doctor diagnosed you with type 2 diabetes. There are actually a few different ways to diagnose diabetes. The first way is to measure a fasting blood glucose. This means that your blood glucose is checked in the lab after not having eaten or drunk anything for at least 8 hours. For this reason, this test is usually done first thing in the morning. Another way to check for diabetes is to drink a 75-gram glucose drink and then have your blood glucose checked (again, in the lab) 2 hours later. And the third way to find out if you have diabetes is also with a blood test that measures your A1C level, which is a measure of your average blood glucose readings over the past 2-3 months. The results of any of these tests need to be confirmed by a second test in order to make sure that the diagnosis of diabetes is correct. It sounds like you were checked for diabetes with a different method than your niece. To be sure, however, you should ask your doctor about which test you had, what your result was and, of course, what the best course of treatment is for you.

You may not need to go on medication, given your latest A1C. However, most treatment guidelines for type 2 diabetes actually DO recommend that you start on medication, usually metformin. This is a discussion that you should have with your doctor.
