Levels of LDL “bad” or “low-density lipoprotein”

  • Less than 100 mg/dL Optimal.
  • 100-129 mg /dL near or above the optimum value.
  • 130-159 mg/dL high limit.
  • 160-189 mg/dL High.
  • 190 mg/dL and above very high.

Levels of HDL “good” or “high-density lipoprotein”

  1. Less than 40 mg/dL (men), less than 50 mg/dL (women) Low HDL cholesterol, this level increases the risk of cardiovascular disease.
  2. 60 mg/dL and high HDL cholesterol (optimal). This level reduces the risk of cardiovascular disease.
