Understanding Lab Tests for Familial Hypertriglyceridemia
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Familial hypertriglyceridemia is a genetic disorder that causes the body to produce excessive amounts of triglycerides, leading to abnormally high levels of these fats in the bloodstream. This inherited condition significantly increases the risk of cardiovascular disease and requires ongoing monitoring through specific blood tests.
Recommended Test
Triglycerides
This test directly measures triglyceride levels in the blood, which is the primary diagnostic marker for familial hypertriglyceridemia. Consistently elevated triglyceride levels, particularly when they exceed 150 mg/dL and especially above 500 mg/dL, can indicate this genetic condition. Regular monitoring is crucial as high triglycerides increase cardiovascular risk, particularly when combined with other factors like high blood pressure or elevated LDL cholesterol.

Diagnosing Familial Hypertriglyceridemia
Since familial hypertriglyceridemia often presents without obvious symptoms, blood testing is essential for diagnosis. The condition is typically identified when triglyceride levels are persistently elevated above normal ranges, especially when there is a family history of similar lipid abnormalities or early cardiovascular disease.
Understanding Your Results
Normal triglyceride levels are typically below 150 mg/dL. In familial hypertriglyceridemia, levels are often significantly higher and may require dietary modifications, medication, or both to manage cardiovascular risk. Regular testing helps monitor treatment effectiveness and adjust management strategies as needed.
