Triglycerides test

Also called: TG, Triglyceride level

Triglycerides are a type of fat in your blood. High levels add to heart risk, and very high levels can cause pancreatitis.

SampleA small tube of blood from a vein in your arm
Fasting?Sometimes 9 to 12 hours
ResultsUsually within 1 to 2 days
Good to knowOne result rarely tells the whole story. Your provider looks at your results together with your symptoms, exam, and other tests.

What the test is

It's part of a lipid panel.

Eating, alcohol, and poorly controlled diabetes raise triglycerides.

Why it's done

  • Heart risk checks
  • Diabetes, obesity, or fatty liver
  • Past pancreatitis

Getting ready and what happens

  • Your provider may ask you to fast for 9 to 12 hours. Avoid alcohol for 24 hours before.

How the test is done

  • A health worker cleans the skin, puts a band around your arm, and draws blood from a vein with a small needle. It takes a few minutes.

What the results mean

ResultTypical range for adults
NormalBelow 150 mg/dL
Borderline high150 to 199 mg/dL
High200 to 499 mg/dL
Very high500 mg/dL or higher

Normal ranges vary from lab to lab and can differ by age, sex, and pregnancy. Your report lists your lab's own range next to each result. A result a little outside the range is often not a problem.

High

Cutting sugar, refined carbs, and alcohol, losing weight, and exercising help. Medicine may be added.

Very high

Raises pancreatitis risk; treatment is needed.

When a result needs quick action

Call 911Severe upper belly pain spreading to the back

Questions to ask your provider

  • What do my results mean for me?
