Purpose of HDL cholesterol blood test

Your doctor may recommend you HDL cholesterol blood test to understand your heart attack and stroke risk. You may have HDL- good cholesterol blood test alone or you may have lipid profile test. Lipid profile test contains these blood tests;

  • Total cholesterol
  • HDL-good cholesterol
  • LDL- bad cholesterol
  • Triglycerides

HDL –good cholesterol level is important for heart and arterial health. HDL is called good cholesterol because it transports the excess cholesterol from tissues to liver for reprocessing. HDL cholesterol reduces heart attack and stroke risk by this way. This process is called reverse transport of cholesterol.

Your doctor may request you to have HDL cholesterol blood test or lipid profile test if you are at higher risk of heart disease. There are some conditions, life style factors and diseases which increase cardiovascular diseases risk.
