LDL Cholesterol Test: Reference Range

LDL cholesterol test plays an important role in determining your risk of developing heart disease and monitoring effectiveness of lipid-lowering therapy.

LDL (low-density lipoprotein) cholesterol, is usually regarded as “bad” cholesterol, because it deposits excess cholesterol in blood vessel walls and leads to arteries hardening and heart diseases.

A 9-12 hour of fasting is required before LDL cholesterol test. During this time period, only water is permitted.

According to NCEP (National Cholesterol Education Program), without any other risk factors, reference ranges of LDL-cholesterol are as follows:

  • LDL-C levels < 100mg/dL (2.59 mmol/L) point to optimal
  • LDL-C levels range between 100-129 mg/dL (2.59-3.34 mmol/L) point to near optimal or above optimal
  • LDL-C levels range between 130-159 mg/dL (3.37-4.12 mmol/L) point to borderline high
  • LDL-C levels range between 160-189 mg/dL (4.15-4.90 mmol/L) point to high
  • LDL-C levels greater than 189 mg/dL (4.90 mmol/L) point to very high
