Triglyceride level
Definition:
This is a test to measure the amount of triglyceride in the blood. Alternative Names:
TG; Triacylglycerol Text Continues Below
How the test is performed:
Blood is drawn from a vein, usually on the inside of the elbow or the back of the hand. The puncture site is cleaned with antiseptic, and an elastic band is placed around the upper arm to apply pressure and restrict blood flow through the vein. This causes veins below the band to fill with blood. A needle is inserted into the vein, and the blood is collected in an air-tight vial or a syringe. During the procedure, the band is removed to restore circulation. Once the blood has been collected, the needle is removed, and the puncture site is covered to stop any bleeding. For an infant or young child, the area is cleansed with antiseptic and punctured with a sharp needle or a lancet. The blood may be collected in a pipette (small glass tube), on a slide, onto a test strip, or into a small container. Cotton or a bandage may be applied to the puncture site if there is any continued bleeding. How to prepare for the test:
Fast for 8 to 12 hours before the test. The health care provider may advise you to withhold drugs that may affect the test (see special considerations). Infants and children: The preparation you can provide for this test depends on your child's age, previous experiences, and level of trust.
