The doc should have told you the answer. If all else fails, go to PrivateMDLabs.com and look it up as best you can. Here is what I see:

Lipid Panel With LDL:HDL Ratio Test Details
Includes: Cholesterol, LDL:HDL ratio; lipid profile, (includes triglycerides).
Patient Instructions: Patient should fast for 12-14 hours before collection of the specimen.

Prostate-Specific Antigen (PSA) Test Details
Includes: Prostate-Specific Antigen (PSA), Serum
Patient Instructions: For accurate test results, no ejaculation during the 24 hours preceding the test.

I believe some of the other tests may require fasting (depending on which particular test they do) ... so it appears the answer is yes, you should fast ... but I am not a doctor. If all else fails, you will have fasted for no reason. I suppose that's better than not being able to do your blood tests.

Speaking from my own experience here...I fasted for 12 hours, and ended up fainting after they took 9 vials of blood for my test. After I came to, the tech/nurse told me I could have only fasted for 8 hours. I live for food every 3 hours...12 hours was just too much for me.

Yep, fasting is not that fun. I do the blood tests early in the morning (~7:00-7:30am) and bring food with me so I can eat when I'm done. I usually only fast about 10-11 hours. I finish up eating by like 8:00-8:30pm the night before and drink water from that point on. This seems to work. My blood glucose levels come back OK so it appears that 10-11 hours works well for the simple tests that I do. The tests the OP listed above are a bit more extensive that anything I have done. I would probably do a full 12 hours before a big panel like that.

Thanks everyone for the replies, I was fasted, They drew about 9 viles.... I was alittle nervous about getting dizzy but I did well LOL. I am used to eating at about 5am but had to wait till about 9:30 for the labs....

Thanks again!

Just dont eat breakfast if you are going in for a morning draw. Also no sex for 48 hours prior to drawing for sex hormones.

Tenn, are you in the Nashville area? I'm trying to find a good doc that has hormone knowledge.
