What This Test Measures

This test includes two primary components: cholesterol and triglycerides. Cholesterol is a type of fat your body needs for cell function but can become harmful in excess, while triglycerides are another form of fat stored in your body.

Why It Matters for Heart Health

High levels of cholesterol and triglycerides can contribute to plaque buildup in your arteries, increasing the risk of heart disease or stroke. Your doctor may use these results to guide treatment or lifestyle recommendations.

How the Test Works

A small blood sample is taken from your arm and sent to a lab. The lab uses specialized tests to measure the amounts of cholesterol (including LDL, HDL, and total) and triglycerides in your serum.

Preparation Tips

To get the most accurate results, avoid eating or drinking anything—except water—for at least 12 hours before your test. If you’re on certain medications, let your healthcare provider know, as they may affect your results.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

What might your results mean?
Elevated cholesterol or triglycerides can signal an increased risk of cardiovascular problems. Your doctor may recommend dietary changes, exercise, or medications if levels are consistently high. Low levels might not raise immediate concerns but could warrant further evaluation if other risk factors are present.
How often should I get this test?
Most adults are advised to have this test every 4–5 years, or more frequently if you have risk factors like high blood pressure, diabetes, or a family history of heart disease. Your doctor will tailor recommendations based on your health status.
Can diet or exercise affect these test results?
Yes! Reducing saturated and trans fats, increasing fiber, and staying active can lower cholesterol and triglycerides. Small, gradual changes often yield the best long-term results.
