Triglycerides are one of the types of fat in the body and your level can be measured with a blood test. The test is more accurate if it is done after fasting from food and drinks for 9 to 12 hours. The normal range for triglyceride level for adults is less than 150 mg/dL.

Triglyceride Ranges

A triglyceride level less than 150 mg/dL is considered ideal for adults, according to the National Cholesterol Education Program. A triglyceride level of 150 to 200 mg/dL is borderline high. A triglyceride result of 200 to 499 mg/dL is high, and levels of 500 mg/dL or more are very high.

There can be some variability in normal triglyceride levels, depending on your age and other factors. Talk with your doctor about your triglyceride level to determine if you need to take action, such as making changes in your diet, exercise or taking medication.

Significance of Triglyceride Level

Maintaining a normal triglyceride level is important for your overall health, but is particularly relevant to limiting your risk for heart disease and stroke. High triglyceride levels promote the development and growth of fat deposits in the arteries that supply blood to your heart, which can lead to a heart attack. Fatty deposits in arteries that supply your brain can also cause a stroke. Inflammation of the pancreas, called pancreatitis, is another possible complication of a very high triglyceride level.
