The test for low-density lipoprotein cholesterol (LDL-C) is used as part of a lipid profile to predict an individual’s risk of developing heart disease and to help make decisions about what treatment may be needed if there is borderline or high risk.
High cholesterol raises your risk of coronary heart disease, atherosclerosis, angina, heart attack, stroke, carotid artery disease, and peripheral arterial disease. So it is necessary to check for it routinely.
an LDL-C level can be evaluated as follows: Less than 100 mg/dL (2.59 mmol/L) — Optimal. 100-129 mg/dL (2.59-3.34 mmol/L) — Near optimal, above optimal. 130-159 mg/dL (3.37-4.12 mmol/L) — Borderline high.
