Lipid disorders are diagnosed with blood tests that measure the level of cholesterol and triglyceride in the blood.

Blood Tests

A small blood sample is taken from a vein in your arm. You may need to fast for several hours, usually overnight, before your blood is taken. The test measures levels of:

  • Total cholesterol
  • LDL cholesterol
  • HDL cholesterol
  • Triglycerides

The results will be one of several factors your doctor will use to determine your overall heart disease risk. What level is ideal for you will depend on your heart disease risk factors such as weight, smoking history, family history, medical history, and age.
