What can a non-HDL cholesterol test tell you?
A non-HDL-C test can help your provider better understand your:
Total amount of “bad” cholesterol that can contribute to plaque buildup in your arteries
Risk for heart attack and stroke over time
Response to treatment, if you’re being treated for high cholesterol
Research indicates that non-HDL cholesterol levels better reflect total harmful cholesterol levels and the risk of heart disease than LDL cholesterol alone.
The Centers for Disease Control and Prevention recommends screening most healthy adults for high cholesterol, including non-HDL cholesterol, every four to six years. Many providers also check non-HDL levels more often if you’re being treated for high cholesterol, or if you have diabetes, obesity, or a family history of high cholesterol or heart problems.
What is being tested?
Non-HDL cholesterol represents the total amount of “bad” cholesterol, meaning the cholesterol that can lead to plaque formation in arteries. These include:
Low-density lipoprotein (LDL) – the primary “bad” cholesterol
Very-low-density lipoprotein (VLDL) – transports triglycerides and converts to LDL
Intermediate-density lipoprotein (IDL) – transitional particle between VLDL and LDL
Lipoprotein(a) – a genetically influenced lipoprotein linked to higher heart disease risk
Chylomicron remnants – leftover particles from dietary fat transport
Measuring non-HDL cholesterol provides a comprehensive snapshot of all potentially atherogenic (plaque-forming) lipoproteins.
Where is the non-HDL cholesterol test typically included?
Non-HDL cholesterol is automatically calculated as part of a lipid panel or advanced lipid panel. It does not require a separate order.
Non-HDL cholesterol testing is included as part of lab testing through Hers. Work with a provider to explore how to improve or optimize your health, and get recommendations to help you do both.
Who should get a non-HDL cholesterol test?
Most adults should have their cholesterol levels — including non-HDL cholesterol — checked at least once every four to six years, or more frequently if they have risk factors for heart disease.
Risk Factors for Elevated Non-HDL Cholesterol:
Family history of early heart disease
High blood pressure
Diabetes or metabolic syndrome
Smoking
Obesity or a sedentary lifestyle
A diet high in saturated fats
Providers may also order a lipid panel more often if you’re being treated for high cholesterol or heart disease.
Kids and teens with risk factors such as diabetes or obesity may also need regular screening.
