In order to know if you have normal cholesterol levels, you need to have a blood test. High Density Lipoprotein (HDL), Low Density Lipoprotein (LDL) and Very Low Density Lipoprotein (VLDL) are the three major types of cholesterol that need to be measured. Total cholesterol level and cholesterol/HDL ratio are also checked to make sure you are within normal cholesterol levels.

Serum lipid values are reported as milligrams per deciliter (e.g. 200 mg/dL) or millimole per liter (e.g. 5.10 mmol/L). mmol/L is the SI unit (Systeme International d'Unites) which is in standard international measurement system. The SI unit considers the numbers of molecules of cholesterol in blood. The mole (symbol: mol) is a unit of amount of substance - the amount that contains as many "elemental entities", (in this case molecules) as there are atoms in 12 g of carbon-12. mmol is millimole or 1/1000 of mole.
In US, India and many other countries, the values for serum cholesterol are reported as mg/dL, while Australia, UK and Europe use SI units. Sometimes the patient gets confused when he (or she) look for lipid cholesterol level values in different units. The following tables can be used to convert the values from one system of units to another.

 In discussions about managing cholesterol to prevent coronary heart disease, lowering LDL (“bad”) cholesterol is often cited as the first goal. But in recent years there has been growing emphasis on low levels of HDL (“good”) cholesterol as an independent risk factor for coronary heart disease. People with HDL cholesterol levels below 40 mg/dL have a significantly elevated rate of heart attacks. About 30% of people with coronary heart disease have low HDL cholesterol levels but normal levels of LDL cholesterol. The American Heart Association (AHA) and the American Diabetes Association currently recommend that HDL levels be above 40 mg/dL for men, and above 50 mg/dL for women. However, the greatest benefits seem to come when a person’s HDL level is over 60 mg/dL. Cholesterol HDL ratio is also important. The total cholesterol to HDL ratio is determined by dividing the total cholesterol level by the HDL cholesterol level. For most people, the goal is to keep this ratio below 5:1, with the ideal ratio being below 3.5:1.
