Is it really big deal if I have cream in coffee 7 hrs before fasting blood work? I find it hard to believe that could badly mess with results.

Then you can have your coffee and cream. If your fasting sugar is 125 you don't have diabetes,if 126 you do. Any difference? ...Read more

When u fast for a routine physical blood work is the gluccose reading only show how you ate the day prior to fasting?

No: The fasting glucose is just that - your baseline fasting glucose. It has nothing to do with what you ate the day before. The point of it is to see your overall health and diet for several months.

Had a fasting blood work done 3 days ago. My glucose level was 274, triglycerides was 356 and A1c was 9.1. Please advise.
