<<Disclaimer: Verify this information before applying it to your situation.>> I guess I should have explained more yesterday. I am no where near being over weight. I called the lab to find out more about this test they are calling insulin. He told me what my doctor said. It is to test to see if I am producing insulin. It is not a hemoglobin A/C. The test say normal range is 6-27 uIU/ml. If anyone understands this please email me. Ginny
