When do I need a triglyceride test, and what does a high result mean?
Triglycerides are usually measured within a lipid panel, but not everyone needs annual testing. Age, cardiovascular risk, prior results and treatment guide the interval. Severe elevation, particularly at 500 mg/dL or more, needs assessment because pancreatitis risk increases, especially at higher levels.

Do I need to fast?
A nonfasting panel may be used initially, while some high results or clinical circumstances need fasting measurements. Follow laboratory and clinician instructions; do not independently stop diabetes or other medication.
Interpret the cause and context
Review sugar and alcohol intake, medicines, diabetes control, thyroid function and inherited causes. Interpretation differs with fasting status, and one result may need confirmation. Levels of 1,000 mg/dL or more require particular attention to pancreatitis risk.
Treatment depends on severity
Dietary changes, activity and management of underlying causes form the plan, sometimes with prescription treatment. Shop-bought fish oil is not an equivalent substitute. Severe persistent upper abdominal pain, especially with vomiting, needs urgent assessment.
