Laboratory: Clinical Biochemistry
Test Name:
TRIGLYCERIDES - (P)
Test Code: TG
Clinical Information:
Test Indications: Triglycerides are synthesized by the liver and also derived from the diet. Increased triglycerides indicate a metabolic abnormality and, along with elevated cholesterol, are a risk factor for atherosclerotic disease. Triglyceride testing is used in combination with cholesterol determination for atherosclerotic risk assessment as well as in the diagnosis and monitoring of lipid and lipoprotein metabolic disorders.
An individual’s level of risk for cardiovascular disease associated with their lipoprotein profile should be managed according to current practice guidelines. Therapy thresholds and targets are based on current guidelines.
