Cholesterol test - Results

Alternative Names

Total cholesterol test

Normal Values:

Total cholesterol is an important measure of both bad and good cholesterol. Other lab tests are done to measure specific amounts of good (HDL) and bad (LDL) cholesterol. A cholesterol breakdown including LDL and HDL is preferred under certain circumstances.

The total cholesterol values listed below are used to target therapy:

Desirable: Under 200 milligrams per deciliter (mg/dL)
Borderline high: 200 to 239 mg/dL
High risk: 240 mg/dL and higher

What abnormal results mean:

In general, a total cholesterol value over 200 mg/dL may mean you have a greater risk for heart disease. However, LDL levels are a better predictor of heart disease, and they determine how your high cholesterol should be treated.

High total cholesterol levels may be caused by:

Low cholesterol levels may be caused by:

Hyperthyroidism
Liver disease
Malabsorption (inadequate absorption of nutrients from the intestinal tract)
Malnutrition
Pernicious anemia
Sepsis
