Low-density lipoprotein test
Normal Values
A healthy LDL level is one that falls in the optimal or near-optimal range.
- Optimal: Less than 100 mg/dL (less than 70mg/dL for persons with a history of heart disease or those at very high risk for atherosclerotic disease)
- Near Optimal: 100-129 mg/dL
- Borderline High: 130-159 mg/dL
- High: 160-189 mg/dL
- Very High: 190 mg/dL and higher
Normal value ranges may vary slightly among different laboratories.
