What's considered normal?

A simple blood test can reveal whether your triglycerides fall into a healthy range:

• Normal — Less than 150 milligrams per deciliter (mg/dL), or less than 1.7 millimoles per liter (mmol/L)
• Borderline high — 150 to 199 mg/dL (1.8 to 2.2 mmol/L)
• High — 200 to 499 mg/dL (2.3 to 5.6 mmol/L)
• Very high — 500 mg/dL or above (5.7 mmol/L or above)

Your doctor will usually check for high triglycerides as part of a cholesterol test, which is sometimes called a lipid panel or lipid profile. You'll have to fast before blood can be drawn for an accurate triglyceride measurement.
