Clinical Significance: A triglyceride test, along with other lipid tests, is used to determine cardiovascular risk in individuals including those with evident cardiovascular disease, known risk factors, a family history of cardiovascular disease, diabetes, kidney disease, hypertension, or those who smoke. Triglyceride testing is also used for the evaluation of hyper- or hypolipidemia.
Limitations: Endogenous unesterified glycerol in the sample will falsely elevate triglyceride values. Ascorbic acid and calcium dobesilate cause artificially low triglyceride values. Intralipid is directly measured as analyte in the assay and leads to high triglyceride results. Acetaminophen use can falsely decrease test results.
