Total cholesterol


Total cholesterol is the sum of all cholesterol measured in a person's blood. This total includes high-density lipoprotein (HDL) cholesterol, which is sometimes called the “good cholesterol,” and low-density lipoprotein (LDL) cholesterol, sometimes called the “bad cholesterol.”

Cholesterol is measured either in milligrams per deciliter of blood (mg/dL) or in millimoles per liter of blood (mmol/L).

  • A total cholesterol level of less than 200 mg/dL (5.17 mmol/L) is desirable.
  • 200 to 239 mg/dL (5.17 to 6.18 mmol/L) is considered borderline high cholesterol.
  • 240 mg/dL (6.21 mmol/L) or higher is considered high cholesterol.

The ratio of total cholesterol to “good” (HDL) cholesterol is also important, especially if total cholesterol is high.
