A member asked:
Recently bloodwork for fasting insulin. how is this different that a glucose tolerance test or a fasting glucose test?
A doctor has provided 1 answer
Different tests: Insulin & glucose are 2 different ways to measure diabetes. Insulin is produced by pancreas to keep sugars under control. We measure glucose to see how well sugars are controlled. Think of glucose as speedometer & Insulin as tachometer (hgba1c is avg trip speed - ask a car nut if this doesn't make sense). Glucose tolerance test requires drinking sugar whereas other 2 tests don't.
