Now that you mention it, Harry, I did come across something along these lines last year. My brother is on coumadin and I take him every month for his INR. Well, the cardio office slipped in a lipids test without telling us, so brother had not fasted. Well the cardio called us, quite alarmed, because brother's triglycerides were up in the 7 or 8 hundreds. I was livid because you don't do that test without fasting, but they insisted he go for another one - after fasting. I asked what it could mean if his triglycerides were truly that high and she said that it could mean diabetes! I didn't know that - but if it turned out he really was heading down that diabetic road, then he'd surely be on insulin eventually. So, what you said, makes sense to me.
