What is the measurement for cholesterol?
serum total cholesterol is measured in mg/dL
Chemistry of the CHOD-PAP method of cholesterol measurement The cholesterol is determined after enzymatic hydrolysis and oxidation. The indicator quinoneimine is formed from hydrogen peroxide and 4-aminoantipyrine in the presence of phenol and peroxidase. Cholesterol Cholesterol ester + H2O ----------------------> Cholesterol + Fatty acids esterase Cholesterol Cholesterol + O2 ----------------------------->Cholestene-3-one + H2O2 oxidase Peroxidase 2H2O2 + phenol + 4-Aminoantipyrine ---------------------------> quinoneimine + 4H2O
Why should the measurement of a person's blood cholesterol be performed at least twice with measurements taken at least one week apart?
LDL, or low density lipoproteins, are the "bad cholesterol" you hear about on television. When your physician orders a lipid panel, there are two ways of determining the LDL, calculated from the HDL and total cholesterol, or direct measurement. The lab which ran your specimen apparently uses the direct measurement, which is the most accurate.
LDL stands for "low-density lipoproteins" and is sometimes referred to as "bad cholesterol". Lipoproteins are organic compounds that allow the blood to carry insoluble molecules such as cholesterol and trigycerides. Lipoproteins with low density are more likely to "drop" their transported cholesterol in the arteries than those with higher density.
Depends on how you measure it. If it is a continuously-variable measurement in a statistical study, using percentages for instance, then it would be a continuous variable. (Cool how that works, eh?) But if it is measured in discrete increments, like the common "cholesterol count" or parts-per-million (ppm) or even molecule by molecule (for a nano-scale experiment), then it's a discrete variable. The difference here is that "discrete" measurements use "whole steps" (a cholesterol count…
The most common cause of high cholesterol is eating foods that are high in cholesterol. Some people's genetics make them more likely to have high cholesterol, but with a diet low in cholesterol and medication, it can be managed. Avoiding food high in cholesterol is the first step in lowering your cholesterol.
Typically, there are three cholesterol levels reported in a cholesterol blood test: total cholesterol, LDL cholesterol, and HDL cholesterol. LDL and HDL cholesterol are measured and discussed as if they are two different types of cholesterol. In fact, that is a bit of a misnomer as there's truly only one waxy substance called cholesterol. The reason two different â€˜typesâ€™ of cholesterol are measured relates to the two very different types of protein that â€˜carryâ€™ the…
