Cholesterol screening helps to determine the cholesterol and fat levels in the blood. Children and adolescents with normal cholesterol level is a thing of the past. Because of the changing lifestyle and junk food trend, even they have a high risk to develop high levels of cholesterol which also increases the risk of developing heart diseases which can affect the blood vessels and the coronary arteries. The main cause of this change is obesity, junk food high in fat, fast food diets, sedentary lifestyle and high cholesterol level in family history. Keeping the blood cholesterol levels at normal is a good way of avoiding high blood pressure and coronary artery diseases.

The blood cholesterol level can vary from individual to individual. Healthy levels of LDL is less than one hundred and thirty milligrams, HDL is greater than thirty five milligrams. If the HDL is less than thirty five milligrams then the adolescent is at a higher risk of developing heart diseases. And LDL more than one hundred and thirty milligrams is dangerous. But a high level of LDL cholesterol is a problem in many citizens of America. And there is an expected increase in number, the figure is unknown, of adolescents who have a family history of high cholesterol levels.

An adolescent or a child who has a parent having high levels of blood cholesterol and family history of heart diseases at an early age, should take cholesterol test from the age of two. Adolescents who are obese also should have lipid test along with cholesterol test. The lipid test shows levels of kinds of fats in blood such as triglycerides, LDL and HDL.
