Triglycerides (Serum) – High-Performance Liquid Chromatography (HPLC) Method

Published: August 9, 2026Updated: August 17, 2026

This test measures the amount of triglycerides, a type of fat found in your blood, using a serum sample. Triglycerides are an important part of your lipid profile and can help assess your risk for heart disease and other health conditions.

Why This Test Might Be Ordered

Your healthcare provider may order this test to evaluate your lipid profile, monitor existing conditions like high cholesterol or diabetes, or check for risk factors related to heart disease, metabolic syndrome, or other health concerns. It’s often done alongside tests for cholesterol (such as LDL and HDL) to give a full picture of your cardiovascular health.

What to Expect Before the Test

No special preparation is usually needed, but you may be asked to fast for 8–12 hours before the test if it’s part of a lipid panel. If you’re unsure, ask your provider about fasting requirements. Bring any medications you’re currently taking, as some may affect results.

What the Test Involves

A healthcare professional will draw blood from a vein in your arm using a small needle. You may feel a brief pinch, but the process is quick. The blood sample is then sent to a lab for analysis using high-performance liquid chromatography (HPLC), a precise method to measure triglycerides accurately.

What the Results Mean

Triglyceride levels alone don’t diagnose a condition—they’re part of a broader lipid profile. High levels may signal an increased risk for heart disease, while very low levels might indicate malabsorption issues or other metabolic disorders. Your provider will interpret results in the context of your overall health and other test results.

Frequently asked questions

How often should I get this test?
This test is typically recommended every 4–6 months if you have high triglycerides or a history of cardiovascular risk factors. If you’re asymptomatic, your provider may suggest it as part of routine cardiovascular screening every few years, depending on your age, family history, and other health factors.
Can lifestyle changes affect my triglyceride levels?
Yes! Diet, exercise, and weight management can significantly impact triglyceride levels. Reducing saturated and trans fats, increasing omega-3 fatty acids (found in fish, flaxseeds), and staying active may help lower triglycerides. Some medications, like fibrates or omega-3 supplements, can also help.
What if my results are outside the normal range?
If your triglycerides are elevated, your provider may recommend further testing (like LDL or HDL levels) or suggest lifestyle changes or medications to help manage them. If they’re very low, you may need additional evaluation to rule out conditions like malnutrition or liver disease.
