basic blood test question

last blood test i got was in june.... i've got a basic blood test set up for tomorrow morning at 9 am...they said don't eat anything 12 hours before the blood test...if i didn't ask about it they wouldn't have told me...so is it important to not eat anything for 12 hours before this basic liver funtion test? thanks...billy

theres no problem not eating for 12 hours..what i was wondering you answered ...i didn't think it was for a liver function test..when the nurse told me i needed to fast it made me wonder why this wasn't told to me before ...this made me question the liver funtion tests i've had in the past....i've been on a pretty strict diet for a year now and i want to make sure what i see and have seen with my tests are accurate.....billy

When I started TX on my first blood test I fasted and got a bad headach from taking my riba on an empty stomach.When I got there I asked and was told I didnt need to fast,liver function only.So if you know for sure or if you can double check.

fasting is not for the liver function tests, it is for other metabolic tests like lipids(cholesterol, etc) and of course like mike said glucose level. Is there a problem why you can not fast for 12 hrs?

I believe the reason may be in order to obtain a fasting glucose level - diabetes test. Mike
