What is a normal LDL range?

The low-density lipoprotein (LDL) cholesterol of healthy persons should be between 100 and 129 milligrams per deciliter of blood, according to Mayo Clinic. The target for individuals at risk for heart disease is below 100 mg/dL; levels below 70 mg/dL are ideal for high-risk patients,

LDL cholesterol is known as 'bad cholesterol' because of its tendency to build up on artery walls, while high-density lipoprotein (HDL) cholesterol is known as 'good cholesterol' as it helps prevent arteries from becoming clogged. 'Total' cholesterol refers to the combination of LDL and HDL cholesterol; the optimal combined cholesterol is below 200 to ensure heart health.
