is fasting required for liver function test - #24516
I am kinda freakin out over my upcoming liver function test. My doctor’s assistant said I need to fast but I read somewhere online that fasting is not always required for liver function test, which makes me super confused. Like, do I really need to fast for the liver function test? I mean, a week ago I had some greasy takeout and now I'm worried if that’ll mess with my results or whatever. Just yesterday I heard my friend saying they didn’t fast for their liver function test and everything turned out fine. Should I have been eating or drinking anything today, or just stick to water? It’s sooo unclear. I wanna prepare correctly but if fasting is required for liver function test, how long should I be fasting? I know some tests require hours, while others may say overnight is fine. I just don’t want to screw this up since my doc is checking for possible liver issues due to some medication I am taking. Anyone have experiences or tips on this fasting for liver function test thing? Like, what are the solid guidelines, or does it vary from one lab to another? Thanks a ton!
