Triglycerides, TG, TRIG

This is a test to check your risk of developing heart disease. It is often done as part of a lipid profile during a regular medical exam or if you are being treated for high triglycerides.

This test measures the amount of triglycerides in your blood. Triglycerides are the body's storage form for fat. Most triglycerides are found in fat tissue. Some triglycerides circulate in the blood to provide fuel for muscles to work. Extra triglycerides are found in the blood after eating a meal when fat is being sent from the gut to fat tissue for storage. The test for triglycerides should be done when you are fasting and no extra triglycerides from a recent meal are present.


The test for triglycerides uses a blood sample. Most often, the blood sample is collected using a needle to collect blood from a vein. Sometimes triglycerides are measured using a drop of blood collected by puncturing the skin on a finger. Testing should be done when you are fasting. For 12 to 14 hours before the test, only water is permitted. In addition, alcohol should not be consumed for the 24 hours just before the test. If you are diabetic and your blood sugar is out of control, triglycerides will be very high.

Ranges for normal findings may vary among different laboratories and hospitals. You should always check with your doctor after having lab work or other tests done to discuss the meaning of your test results and whether your values are considered within normal limits.


Your caregiver will go over the test results with you and discuss the importance and meaning of your results, as well as treatment options and the need for additional tests if necessary.


It is your responsibility to obtain your test results. Ask the lab or department performing the test when and how you will get your results.
