Cholesterol is a soft, waxy fat that your body needs to function properly. However, too much cholesterol can lead to heart disease, stroke, atherosclerosis, a clogging or hardening of your arteries.
Low-density lipoprotein (LDL) cholesterol is referred to as “bad” cholesterol and High-density lipoprotein (HDL) cholesterol is referred to as “good” cholesterol because it helps remove LDL cholesterol from your blood.
Generally, you’re required to fast, consuming no food or liquids other than water, for nine to 12 hours before the test. Some cholesterol tests don’t require fasting, so follow the instructions provided by your doctor.
Total blood cholesterol level: High risk: 240 mg/dL and above. Borderline high risk: 200-239 mg/dL. Desirable: Less than 200 mg/dL.
