High triglycerides are often a sign of other conditions that increase the risk of heart disease and stroke as well, including obesity and metabolic syndrome — a cluster of conditions that includes too much fat around the waist, high blood pressure, high triglycerides, high blood sugar and abnormal cholesterol levels.

Triglycerides are a type of fat (lipid) found in your blood. When you eat, your body converts any calories it doesn't need to use right away into triglycerides. The triglycerides are stored in your fat cells. Later, hormones release triglycerides for energy between meals.

A few products are available to test lipid levels, including triglycerides, at home. There are two types of home testing: those where you collect the sample at home and then mail it away to a laboratory for testing and those where you conduct the test yourself at home (self-monitoring).

How is it used? Blood tests for triglycerides are usually part of a lipid profile that is used to help identify an individual's risk of developing heart disease and to help make decisions about what treatment may be needed if there is borderline or high risk.

How Is the Triglyceride and Cholesterol Test Done? The test for cholesterol and triglycerides consists of a simple blood test, which today can be done even with the small amount of blood obtained by a needle prick.

A simple blood test can reveal whether your triglycerides fall into a healthy range. Normal — Less than 150 milligrams per deciliter (mg/dL), or less than 1.7 millimoles per liter (mmol/L) Borderline high — 150 to 199 mg/dL (1.8 to 2.2 mmol/L) High — 200 to 499 mg/dL (2.3 to 5.6 mmol/L)

For adults, triglyceride test results are categorized as follows: 1  Desirable: Less than 150 mg/dL (1.7 mmol/L) 2  Borderline high: 150 to 199 mg/dL (1.7-2.2 mmol/L) 3  High: 200 to 499 mg/dL (2.3-5.6 mmol/ 4 L) Very high: Greater than 500 mg/dL (5.6 mmol/ L)

Blood levels of cholesterol and triglycerides have been strongly correlated with a person’s risk of developing coronary artery disease (CAD) and other types of cardiovascular disease. Experts now recommend that blood testing for lipid levels sould be done in everyone. Read about cholesterol and triglycerides.

Why do high triglycerides matter? Although it's unclear how, high triglycerides may contribute to hardening of the arteries or thickening of the artery walls (atherosclerosis) — which increases the risk of stroke, heart attack and heart disease.

Niacin, sometimes called nicotinic acid, can lower your triglycerides and your bad cholesterol (low-density lipoprotein, or LDL, cholesterol). It's typically reserved for people who have triglyceride levels over 500 mg/dL (5.7 mmol/L). Don't take over-the-counter niacin without talking to your doctor first.
