Triglyceride in Plasma (High-Performance Liquid Chromatography)

Why Is This Test Done?

Your healthcare provider may order this test to monitor your risk of heart disease, diabetes, or other metabolic disorders. It’s often used alongside other lipid tests (like cholesterol levels) to create a full picture of your cardiovascular health. Triglycerides can also be checked if you have symptoms like unexplained fatigue, rapid weight gain, or signs of high fat levels in your blood.

What Does a High or Low Level Mean?

High triglyceride levels may increase your risk of heart disease, stroke, or pancreatitis. Low levels are generally not a concern unless they’re due to a medical condition like malnutrition or certain medications.

How Is the Test Performed?

A small blood sample is taken from a vein in your arm. The blood is then sent to a lab where it’s analyzed using high-performance liquid chromatography (HPLC) to measure triglyceride levels.

What Should You Do Before the Test?

To get the most accurate results, avoid eating or drinking anything (except water) for 9–12 hours before the test. If you’re on medications that affect lipids, like statins, let your provider know. Some medications, supplements, or recent exercise can temporarily affect triglyceride levels.
