Variability of cholesterol reading?

Hi, I happened to go to an all-u-can-eat Chinese buffet, an hour before getting a blood test. (I don't eat food like that often.) I got a cholesterol reading of 235. How much does blood cholesterol vary after meals?

Let us just think a tiny bit about this question. The guy eats and one hour later gives a blood sample for a cholesterol test. The majority of the cholesterol in anyones blood is made by his own body.
It is not simply cholesterol absorbed from the food he eats. So there is no reason at all that eating a big meal and having a blood draw an hour later would impact either LDL or HDL levels one iota.

How about triglycerides? The medical people keep calling triglycerides cholesterol even thou triglycerides are not in the slightest chemically related to cholesterol other then both are made from carbon, hydrogen and oxygen. Nor are triglycerides the chemical precursors that your body uses to sythesize cholesterol. Never the less the medical people call triglycerides cholesterol and have a conversion factor that they use. So could food eaten an hour before a blood draw impact triglyceride levels? Particularly Chinese food which is not usually particularly fatty? I think it is very unlikely that the increase would be statistically significant. Particularly in light of the wide scatter expected in cholesterol determinations.

I have a paper someplace I am not going to bother to dig out. The subject of the paper was the noise level in cholesterol analyses when duplicate samples were analyzed at teaching hospital labs. One should expect such labs to be some of the better labs in terms of doing the analyses more or less correctly. The paper presented results which said that the two standard deviation noise level was +/- 14.7% relative. In other words if your total cholesterol came out 200 and you wanted to be 95% confident of the range the true number was in that range would be 170 to 230. With this kind of noise level seeing a small change due to eating a meal is out of the question.

I know this is a long answer and much to complicated for chungy child to possibly understand. His simple one liner answer sure looks like incompetent garbage advice once again unless he can provide a peer reviewed publication to back up his statement.

Dear little chungy;

First of all medquest asked a perfectly reasonable question. Then you gave an answer that is the opposite of the answer you gave to the same question a year or two ago. So, if there is new information why not post it?

The truth is you continue to shoot from the hip without thinking. And it is getting worse all the time. Two weeks ago you tell an elderly lady her problem is she is overweight without even knowing her weight!
Then you tell her to see a cardiologist when her problem is very unlikely to even be a circulatory problem. To make matters worse she lives in a country with rationed medical care. It will take her three months to get to a doctor. When you are 90 something three months is way too long to wait to simply find out you are at the wrong doctor.
It is bad enough in the US where it can easily take six weeks to see a specialist the first time unless you are on deaths doorstep.

The only good thing I can say about you is you are not praying to your false deity for my soul. You are a liar. You are not very smart.
You are not thoughtful. You spout facts that are made of thin air. I thought you took the hypocratic oath? Then why do you not try to help people rather then passing out nonsense?

The answer to the above is straightforward. You need serious psychiatric help and fast. I have seen lots of sad people who were mentally ill. I suggest you find help before you seriously harm someone. Posting under all those false names is not helping you. It is a real shame that the medical community is so poor at self policing. Most of science works far better.

blah blha bhla spite is nice and idiots make the loudest noises.
