LDL stands for low-density lipoprotein. It's also sometimes called "bad" cholesterol. Lipoproteins are made of fat and protein. They carry cholesterol, triglycerides, and other fats, called lipids, in the blood to various parts of the body. LDL can clog your arteries.
Your LDL level is what doctors watch most closely. You want your LDL to be low. Too much LDL, commonly called "bad cholesterol," is linked to cardiovascular disease. If it gets too high, you will need treatment.
A healthy LDL level is one that falls in the best or near-best range.
Best: Less than 100 mg/dL (less than 70 mg/dL for persons with a history of heart disease or those at very high risk)
Near Best: 100 - 129 mg/dL
Borderline High: 130 - 159 mg/dL
High: 160 - 189 mg/dL
Very High: 190 mg/dL and higher
