The HDL cholesterol is normal if it is greater than 40 to 60 milligram per deciliter.
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.
In general, healthy lipid levels help to maintain a healthy heart and lower the risk of heart attack or stroke.
If HDL-C is less than 40 mg/dL (1.0 mmol/L) for men and less than 50 mg/dL (1.3 mmol/L) for women, there is an increased risk of heart disease that is independent of other risk factors, including the LDL-C level.
A typical level of HDL-C is between 40-50 mg/dL (1.0-1.3 mmol/L) for men and between 50-59 mg/dL (1.3-1.5 mmol/L) for women and is associated with average risk of heart disease.
- For children, teens and young adults:
If HDL-C is less than 40 mg/dL (1.04 mmol/L), there is an increased risk of heart disease that is independent of other risk factors, including the LDL-C level.
A level of HDL-C between 40 and 45 mg/dL (1.04-1.17 mmol/L) is borderline. A level of HDL-C greater than 45 mg/dL (1.17 mmol/L) is acceptable.
