Triglycerides
Use
Measurement of triglyceride levels in blood is a key component of assessing lipid metabolism and cardiovascular risk, commonly included in lipid panels. Elevated triglycerides are associated with increased risk of atherosclerotic cardiovascular disease, pancreatitis, and metabolic syndrome, while low levels may indicate malnutrition or other metabolic disorders.
Special Instructions
Often ordered as part of a lipid panel; if triglyceride level is > 400 mg/dL, direct LDL cholesterol may be performed at additional charge (CPT 83721). Patient should fast 9–12 hours prior to collection to ensure accurate triglyceride measurement.
Limitations
Interpretation may be affected by non-fasting samples, lipemic specimens, or interference. Direct LDL measurement may be required if triglycerides exceed measurement range. Automated assays may yield unreliable results in extreme triglyceride concentrations.
