What Are the Normal Ranges for HDL and LDL?
The normal range for LDL cholesterol is less than 190 milligram per deciliter, according to MedlinePlus. The HDL cholesterol is normal if it is greater than 40 to 60 milligram per deciliter.
LDL levels between 70 and 189 milligram per deciliter are considered too high for diabetics or those who have a high risk of heart disease, reports MedlinePlus.
LDL or bad cholesterol should be kept low as it contributes to plaque that clogs the arteries and may cause heart attack or stroke, according to the American Heart Association. A high level of HDL or good cholesterol is ideal because it helps remove LDL from the arteries of the heart.
