Glucose Test Results

I talked to the doctor's office on Friday afternoon and they said everything looked normal for the latest glucose test. They did, however, forget to take blood samples four times. They took the last three but forgot to take a sample before I had the glucose solution. They seemed confident they could get that number based on the levels from the other three blood draws, plus they have the levels from the first time I took the simpler glucose test. All I know is that I don't want to have to take the test again.
