Quick Question for a doctor in the house about a blood test

I just had a blood test for a physical this morning. My doctor told me not to eat anything the morning of the blood test, which I did, I didn't eat anything. But, I had a sandwich before I went to bed (I'm always very hungry before I go to bed). About 8 or 9 hours passed before I had my blood drawn.

On my out of the lab though, I noticed a flier saying I needed to fast for 12 hours. I didn't think anything of it until I was on my home. Do you think enough time went by before my test as to not throw off my results?

I'll probably call my doctor's office tomorrow, but I wanted to see if anyone knew offhand.

If they say 12 they mean 12.

Call the MD office and explain what happened.

The doctor said it was mainly for blood cell counts and cholesterol as a part of my physical. My copy of prescription lists comprehensive health panel, lipid profile, cbc, psa, and T7-TSH for the exact tests.
 
Eh 8 hours should be plenty for a lipid profile, especially just a sandwich...the rest dont matter concerning food AFAIK
 
Um no 8 is NOT good enough. I'm no doctor but I have my blood "tasted" every 6 months for my triglycerides and such. According to my doctor sometimes 12 hours is not enough but can get most people by. It also matters what you ate. A sandwich will most likely show up and can look like high sugar levels.

Unless he was insulin dependant he wouldnt have high sugar levels 8 hours later...and besides some/most insulin dependant diabetes take insulin before they goto bed depending on their sugar levels.

We do lipid panels in the hospital all the time and I can tell you most of them(patients) probably ate within 8 hours, generally they are looking more if your levels of trigly's, LDL, HDL etc are uber high, or if you have early signs of hypertryglyceridemia/hypercholestroemia and can also help detect possible heart issues as well
