Cholesterol Estimation and Measurement

A sample of your blood is taken either from a ear-lobe prick or finger-prick sample with the help of a desk top machine, or a sample is taken from vein and it is sent to hospital. This article gives information about cholesterol estimation and measurement.

Concentration of blood cholesterol is measured in millimoles per litre. The normal value may vary between countries (mainly due to differences in intake of fat). For individuals, levels of blood cholesterol can vary from 3.5 mmol to 15mmol.

Also they can vary from day to day and hour to hour. Usually, desirable levels are regarded to be under 5.2 mmol and usually levels are regarded as high when over about 6 mmol.

Often, blood fats sophisticated measurements include triglyceride. Except in diabetes, triglycerides measurement is rarely of practical value and also in inherited familial hypercholesterolaemia, which is a special case. Commonly, high values are commonly associated with high alcohol consumption, being fat, or both.

Triglycerides and cholesterol fraction measurements are more complex and also costly for the laboratory. But, they are more bother for the individual being tested. Measurements for HDL cholesterol and total cholesterol can be accurate, but triglyceride and VLDL and LDL cholesterol can be measured accurately only after a fasting for minimum time of 12 hours.

Measurement of cholesterol levels in the blood should be done in people with the risk for coronary heart disease, people with glucose intolerance or diabetes, people who smoke, people with high blood pressure and people with a coronary heart disease family history affecting a parent, sister or brother before reaching the age of 60 years.

In these people, not only screening is done, but also measurements have to be done two to three times in order to get accurate values of blood cholesterol level. Before you consider any treatment, make sure your values are accurate.
