Yesterday I had my total cholesterol checked. It wasn't a lip-protein profile so I assume I didn't have to fast. Well, I was hungry so I ate a hamburger, fries and coke 3-4 hours before i took the the test.
I got the results back today and they said my total cholesterol is 187 and my HDL is 80.
My question is did the food eat prior to the test affect the numbers OR not? Last year my total cholesterol was 167, it looks like it has risen.

As far as I know, all cholestorol tests are to be taken fasting, which means no food or drink other than water for 12 hours before the test. I usually do them first thing in the morning, so I don't have to starve through the day. Also the lines are ususally shorter at 7:30AM (I guess not too many people want to face the needle first thing in the morning). Normally, they ask you if you are fasting, and if you have eaten anything, they won't give you the test.
Eating prior to getting blood lipids measured will have the biggest impact on triglyceride levels (excess carbohydrates and fat consumed will temporarily raise triglyceride levels). It won't affect HDL or LDL levels that much. But since triglycerides (20% of them at least) are a component of the total cholesterol number, this will be impacted also.
Total Cholesterol = HDL + LDL + Trig/5
