Why This Test Matters

Triglycerides are a form of fat that travels through your bloodstream. High levels can increase your risk of developing heart disease, stroke, or other health problems. This test helps your healthcare provider monitor your overall cardiovascular health and guide treatment decisions.

What to Expect Before the Test

No special preparation is typically needed, but you may be asked to fast for 8–12 hours before the test to get the most accurate results. Your healthcare provider will provide specific instructions if needed.

How the Test Works

A small blood sample is drawn from a vein in your arm. The blood is then sent to a lab where it is analyzed to measure the amount of triglycerides present.

What the Results Mean

The results help determine whether your triglyceride levels are within a healthy range or if further action is needed, such as lifestyle changes or medication.
