Fasting lipid measurement test

A blood sample is taken from a vein in your arm — your nurse or phlebotomist will explain the procedure to you. If you're concerned about fainting or have worries about needles, you may be able to have a blood sample taken while you're lying down. If the procedure has made you feel lightheaded, you'll be invited to remain in the department until you feel fully recovered.

Your consultant or nurse will explain the test to you and answer any questions you may have. You should let them know if you are taking any blood thinning medication or if you have a condition that makes you more likely to bruise or bleed.

Please fast (don't eat anything) for around nine hours before your blood test, though you may drink a little water. Having a blood sample is a very simple and safe procedure, but it's normal to feel a little anxious. You're welcome to bring a friend or relative with you to your appointment.

You may have some discomfort, redness or bruising in the area after your test, but this shouldn't last long. Your test results will usually be available within a couple of days. Your consultant will explain how to understand the different types of lipids measured.

Increased levels of low-density lipoprotein could mean an increased risk of heart disease or stroke, while excess triglycerides could mean an increased risk of developing cardiovascular disease. Depending on your results, your consultant might recommend diet, medication or lifestyle changes to help lower your cholesterol.
