"Normal" cholesterol levels vary. However, as a general guideline, total cholesterol should be under 200 mg/dL, LDL should be under 100 mg/dL, and HDL should be over 40 mg/dL. (Cholesterol levels are measured in milligrams [mg] of cholesterol per deciliter [dL] of blood.) Although not a form of cholesterol, triglycerides are often measured when testing to determine if a person has normal cholesterol levels.
