Do you need to fast for liver enzyme test?

Most labs prefer a fasting of 8-10 hours for a liver enzyme test to ensure the results are highly accurate. Don't worry, just schedule it early in the morning so you can eat right after.

Sadly, yes! You have to stay away from your midnight snacks and morning chai for at least 10 hours. It is tough for foodies like us, but the thought of a huge breakfast right after the blood draw is the best motivation!

Actually, you do need to fast for around 10 hours, yaar. My dad had this test last week and the lab guys told us that eating food can fluctuate the liver enzymes quite a bit. So skip the morning breakfast till it is done.

When I had my checkup at Lilavati, they strictly told me to fast overnight for my liver panel. Food can alter enzyme levels temporarily. It is always best to ask your doctor clearly before scheduling.

I was looking into this earlier and read that while simple enzyme tests sometimes don't require fasting, complete liver function panels almost always do. It is super confusing, so I guess calling the lab is the safest bet.
