American Heart Association Recommendations

Total blood cholesterol is the most common measurement of blood cholesterol. It's the number you receive as test results. Cholesterol is measured in milligrams per deciliter of blood (mg/dL). Knowing your total blood cholesterol level is an important first step in determining your risk for heart disease. However, a critical second step is knowing your HDL ("good") cholesterol level.

Blood cholesterol for adults is classified by levels. Your doctor must interpret your cholesterol numbers based on other risk factors such as age, family history, smoking and high blood pressure.
