@GtHawk When I was diagnosed, the doctor did not rely on one blood draw, but several. Also, there had to be fasting. One blood draw does not necessarily mean you are a full blown diabetic.
Whether you might need medication may depend on a number of factors, including other health conditions. When I was diagnosed, I had already had a cardiac arrest and other tests confirmed kidney disease. Plus I was obese. Diet and exercise would not work at that stage.
There is an assortment of new meds out there, but my doctor believes in the old ones. He figures since they have been around for a while, the side effects, interactions and risks are well known as well as whether or not they are effective. A lot of the newer meds might have problems we aren't aware of yet. Besides, the oldies all have generic equivalents and are cheap with prescription insurance coverage. I just paid $7.50 for 90 days of Glipizide. Not bad.
I've had no problems with Glipizide. Just beware if the doctor prescribes Metformin. It works well for a lot of people, but I had some bad side effects. I didn't complete even the first bottle.
