Cholesterol levels include total cholesterol levels, LDL cholesterol levels, and HDL cholesterol levels. Total cholesterol levels may be misleading, because a person can have a healthy total cholesterol level and still have a low HDL cholesterol level or a high LDL cholesterol level. A total cholesterol level over 240 mg/dL is high, and a level between 200 and 239 mg/dL is borderline high. A total cholesterol level under 200 mg/dL is a healthy level. If your total cholesterol is higher than 240 mg/dL, your risk of heart disease and stroke is higher. However, the higher your level of HDL cholesterol, which is the "good cholesterol," the better.
