Homocysteine Test Helps Determine Heart Disease Risks and Treatment

Also known as: Plasma total homocysteine

Your doctor may order a blood test for the amino acid, homocysteine, to help assess your risk for stroke or a heart attack.  You may be at greater risk if your blood homocysteine levels are found to be high. Your doctor also may order this test following a stroke or heart attack to help determine your best treatment options.

Preparation and Procedure

  • You do not need to schedule an appointment for this test.
  • Before going to the lab, you will need to follow your doctor’s fasting instructions.
  • Arrive at the lab and sign in at the desk. Be sure to wear clothing with sleeves that are easily rolled up.
  • A phlebotomist will draw blood from your arm for a specimen.

Time Required

It takes approximately 45 minutes to register at the lab and complete your blood draw. Results from the test are typically sent to your doctor within days; be assured, however, that any critical results are communicated immediately. Your doctor will discuss the results with you once he or she has reviewed them.
