Triglycerides Test
The triglycerides test measures the concentration of triglycerides in a blood sample. Quest describes it as used alongside cholesterol testing to help assess lipid metabolism and coronary heart disease risk.
About this test
Triglycerides are a component of lipid metabolism measured through spectrophotometric analysis of a serum sample. Quest notes this test has been used in the diagnosis and treatment of diabetes mellitus, nephrosis, liver obstruction, and other diseases involving lipid metabolism or endocrine disorders.
Combined with HDL and total cholesterol, Quest describes the triglycerides result as providing information for assessing coronary heart disease risk, which is why it is often ordered together with a lipid panel rather than alone.

What this test looks at
The test reports a single value: the concentration of triglycerides in a serum sample, measured by spectrophotometry. Quest lists this test as used in the diagnosis and treatment of diabetes mellitus, nephrosis, liver obstruction, and other diseases involving lipid metabolism or endocrine disorders.
How it's often used alongside other tests
Quest describes triglycerides, combined with HDL and total cholesterol, as providing information for assessing coronary heart disease risk. Because of that, the test is frequently ordered as part of a lipid panel rather than by itself, and preparation differs depending on which way it is ordered.
