Measures the amount of HDL cholesterol in blood. HDL helps transport cholesterol away from artery walls to the liver.

What is this test?

This blood test measures the concentration of high-density lipoprotein (HDL) cholesterol in serum or plasma. HDL is a type of lipoprotein that carries cholesterol through the blood and helps deliver it to the liver for processing.

Why might I need this test?

HDL cholesterol is commonly included in a lipid panel to help assess cardiovascular risk. It may be ordered during routine screening, for follow-up of cholesterol treatment, or when another type of cholesterol is unexpectedly high.

How is the test performed?

A blood sample is drawn from a vein and analyzed in the laboratory to determine the amount of HDL cholesterol. It is usually reported with the other results from a lipid panel.

How do I prepare for the test?

Fasting is often unnecessary for routine HDL testing, but follow the instructions provided by your clinician or laboratory. If the test is part of a complete lipid panel, fasting may be requested in some circumstances.

Reference range

Adult males: >40 mg/dL; Females: >50 mg/dLN/A

Specimen: serum

Fasting for 12-14 hours preferred. Water is permitted. Avoid alcohol for 24 hours before the test.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

A higher HDL cholesterol level is generally considered favorable for cardiovascular health, while a lower level may increase cardiovascular risk. Results should be interpreted with LDL cholesterol, triglycerides, overall lipid levels, and personal risk factors such as smoking, diabetes, high blood pressure, and family history. A single HDL result does not diagnose heart disease or determine treatment by itself.

Short name

HDL Cholesterol

Frequently asked questions

Does a high HDL cholesterol level guarantee protection from heart disease?
No. Higher HDL is generally associated with lower cardiovascular risk, but it does not eliminate the risk from other factors and should be interpreted with the rest of the lipid panel.
Do I need to fast before this test?
Often not, although instructions can vary. If your clinician ordered a complete lipid panel and requested fasting, follow those instructions.
Can medications or lifestyle changes affect the result?
Yes. Weight changes, physical activity, smoking, diabetes, and cholesterol-lowering medicines can influence HDL cholesterol. Your clinician can explain how your result fits with your overall health.
