What Are Triglycerides and Cholesterol?
Triglycerides are a type of fat found in your blood. Cholesterol is a waxy substance that your body needs but can become harmful if levels are too high. Both play roles in heart disease risk and overall cardiovascular health.
Why Is This Test Done?
Your doctor may order this test to check for high cholesterol or triglycerides, which can increase the risk of heart disease, stroke, or other health issues. It’s often part of routine check-ups or if you have symptoms like fatigue, chest pain, or a family history of heart problems.
What to Expect Before the Test
No special preparation is usually needed, but you may be asked to fast (not eat or drink) for 12 hours before the test if triglycerides are measured separately. Bring any medications you’re currently taking.
During the Test
A healthcare provider will draw blood from a vein in your arm. You may feel a slight pinch, but it usually doesn’t cause discomfort. The blood sample is then sent to a lab for analysis.
Reference range
Optimal: <100 mg/dLN/A
Fasting for 12-14 hours preferred. Water is permitted. Avoid alcohol for 24 hours before the test.

Frequently asked questions
High levels of triglycerides or cholesterol can clog arteries, leading to heart disease, high blood pressure, or other serious health problems. Your results help determine if lifestyle changes, diet, exercise, or medication are needed to manage your health.
High triglyceride or cholesterol levels may signal the need for dietary adjustments, increased physical activity, or medical treatment. Low levels might not require action unless they’re linked to other health conditions.
