The total cholesterol level account for the low-density lipoprotein (LDL) and the high-density lipoprotein (HDL) and the triglycerides (fats and oils). LDL is also known as the 'bad' cholesterol because it caused blockage of arteries, while HDL are 'good' protein because they reduce the cholesterol build-up. The normal total cholesterol level is less than 200 mg/dL.
