Triglycerides in Serum or Plasma

Why This Test Matters

Triglycerides are a form of fat that your body uses for energy. High levels can increase your risk of developing heart disease, stroke, or type 2 diabetes. This test helps doctors monitor your lipid profile and guide treatment plans for managing cholesterol and 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 full lipid panel. If you’re unsure, ask your healthcare provider. Blood is drawn from a vein in your arm, similar to other blood tests.

How the Test Works

Your blood sample is analyzed to measure the concentration of triglycerides. The test uses a chemical reaction to detect and quantify these fats, often measured in milligrams per deciliter (mg/dL). Results help determine whether your triglyceride levels are within a healthy range or if further action is needed.

What the Results Mean

Results are typically reported as a single number representing your triglyceride concentration. While specific reference ranges vary by lab, high levels (often above 150 mg/dL) may signal increased cardiovascular risk, while very low levels (below 50 mg/dL) may warrant further evaluation for metabolic or nutritional concerns.
