Description

Cholesterol and triglyceride tests are blood tests used to measure the levels of fats (cholesterol and triglycerides) in your blood. Cholesterol circulates in the bloodstream bound to proteins, forming complexes known as lipoproteins. The body uses cholesterol to build cells and produce hormones.
