What is this test?
This test measures the amount of triglycerides in your blood.
Triglycerides are one of several types of fats in your blood. Other kinds are LDL
("bad") cholesterol and HDL ("good") cholesterol.
Knowing your triglyceride level is important, especially if you have diabetes, are overweight
or a smoker, or are mostly inactive. High triglyceride levels may put you at greater
risk for a heart attack or stroke.
This test is part of a group of cholesterol and blood fat tests called a fasting lipoprotein
panel, or lipid panel. This panel is recommended for all adults at least once every
5 years, or as recommended by your healthcare provider.
Knowing your triglyceride level helps your healthcare provider suggest healthy changes
to your diet or lifestyle. If you have triglycerides that are high to very high, your
provider is more likely to prescribe medicines to lower your triglycerides or your
Why do I need this test?
You may need this test as part of a routine checkup. You may also need this test if
you're overweight, drink too much alcohol, rarely exercise, or have other conditions
like high blood pressure or diabetes.
If you are on cholesterol-lowering medicines, you may have this test to see how well
your treatment is working.
What other tests might I have along with this test?
Your healthcare provider will order screening tests for LDL, HDL, and total cholesterol.
What do my test results mean?
Test results may vary depending on your age, gender, health history, the method used
for the test, and other things. Your test results may not mean you have a problem.
Ask your healthcare provider what your test results mean for you.
Results are given in milligrams per deciliter (mg/dL). Normal levels of triglycerides
are less than 150 mg/dL.
Here are how higher numbers are classified:
If you have a high triglyceride level, you have a greater risk for heart attack and
A triglyceride level above 150 mg/dL also means that you may have an increased risk
for metabolic syndrome. This is a cluster of symptoms including high blood pressure,
high blood sugar, and high body fat around the waist. These symptoms have been linked
to increased risk for diabetes, heart disease, and stroke.
High triglycerides levels can also be caused by certain diseases or inherited conditions.
If your triglyceride level is above 200 mg/dL, your healthcare provider may recommend
Limit high-fat foods containing saturated fats. These are animal fats found in meat,
butter, and whole milk.
Limit trans fats, which are found in many processed foods like chips and store-bought
Cut back on drinks with added sugars, such as soda
Limit your alcohol intake
Control your blood pressure
Exercise for at least 30 minutes a day, 5 days a week
Limit the calories from fat in your diet to 25% to 35% of your total intake
If your triglycerides are extremely high—above 500 mg/dL—you may have an added risk
for problems with your pancreas. You will likely need medicine to lower your levels
along with recommended changes in diet and lifestyle.
How is this test done?
The test is done with a blood sample. A needle is used to draw blood from a vein in
your arm or hand.
Does this test pose any risks?
Having a blood test with a needle carries some risks. These include bleeding, infection,
bruising, and feeling lightheaded. When the needle pricks your arm or hand, you may
feel a slight sting or pain. Afterward, the site may be sore.
What might affect my test results?
Not fasting for the required length of time before the test can affect your results.
Certain medicines can affect your results, as can drinking alcohol.
How do I prepare for the test?
If you have this test as part of a cholesterol screening, you will need to not eat
or drink anything but water for 9 to 12 hours before the test. Tell your healthcare
provider about all medicines, herbs, vitamins, and supplements you are taking. This
includes medicines that don't need a prescription and any illegal drugs you may use.
