Triglycerides Test
A triglycerides test measures the amount of fat in your blood, helping to assess your risk for heart disease and stroke.
What is a triglycerides test?
Triglycerides are a type of fat used by your body for energy. While necessary for health, high levels in the blood can damage arteries and increase the risk of coronary artery disease, heart attack, and stroke. Extremely high levels can also cause acute pancreatitis. Common causes of high triglycerides include poor diet (high fat/sugar), lack of exercise, obesity, diabetes, thyroid disease, and certain medications.
What is it used for?
The test is used to evaluate your risk for heart disease and stroke. It is typically performed as part of a lipid profile, which also measures cholesterol levels. This information helps providers calculate your overall cardiovascular risk.
Why do I need a triglycerides test?
Testing is often part of a routine checkup. Frequency depends on age, sex, and risk factors. Generally, healthy individuals should be tested every five years starting in young adulthood, with more frequent testing recommended for those over 65 or those with risk factors like smoking, obesity, diabetes, or a family history of early heart disease.
What happens during a triglycerides test?
A health care professional will draw a small amount of blood from a vein in your arm. The procedure takes less than five minutes.
Will I need to do anything to prepare for the test?
You may be required to fast (no food or drink) for 9 to 12 hours before the test. Follow your provider's specific instructions.
Are there any risks to the test?
There is very little risk, with only minor potential for temporary pain or bruising at the needle site.
What do the results mean?
Results are measured in mg/dL. For adults, levels under 150 mg/dL are considered healthy. Levels from 150–199 mg/dL are borderline high, 200–499 mg/dL are high, and 500 mg/dL or higher are very high. High levels may be managed through lifestyle changes, such as a heart-healthy diet, regular exercise, weight management, and smoking cessation, or through medication if necessary.
