Normally, before I knew I had Hep C and when I did other lab work, I fasted
because usually they were doing a blood glucose
level and cholesterol levels.
Since I have been on treatment, I have not fasted for any tests. There really is no way to fast for lab and still pack in the 20 grams of fat and a meal 4 times a day.
If you want to be absolutely 100% sure, call your docs office and get the lab's number and call the lab.
