Cholesterol Level Test

Cholesterol Level Test

What is a Cholesterol Level Test?

Blood cholesterol levels are measured with a simple blood test. A blood sample is taken and used to determine the amount of bad cholesterol (low-density lipoprotein, or LDL) good cholesterol (high-density lipoprotein, or HDL) and triglycerides (other fatty substances) in your blood.

Before these tests, you may be asked not to eat for 10-12 hours before the tests including when you are asleep at night. This ensures that the food you have ingested is fully digested and does not affect the test. 

A newer type of test that measures non-high density lipoprotein (non-HDL) is being used more often as its thought to be more accurate in estimating cardiovascular disease risk than LDL.

Who should be tested?

  • You may have your blood cholesterol levels tested if you fit the following medical history/background:
  • You have been diagnosed with coronary heart disease, stroke or mini stroke or peripheral arterial disease (PAD)
  • You are over 40 years of age
  • You have a family history of early cardiovascular disease
