What Is HDL Cholesterol Test?
HDL Cholesterol, often referred to as “good” cholesterol helps remove the low-density lipoprotein (LDL) or bad cholesterol from the bloodstream. HDL cholesterol test measures the levels of HDL in the blood stream. High levels of HDL are associated with lowering the risk of heart disease and stroke, while low levels may increase the risk of cardiovascular problems.
HDL cholesterol is often tested as a part of Lipid panel, which measures total cholesterol, LDL cholesterol and triglycerides. The panel is used to assess a patient’s risk of developing heart disease, monitor effectiveness of medications or lifestyle changes and guide treatment decisions. The test is recommended for adults as part of routine health screenings, especially for those with risk factors such as obesity, diabetes, high blood pressure or a family history of heart disease.
How is the Test Performed?
Preparation
Fasting for 9-12 hours is recommended to ensure accurate results, especially if a full lipid profile panel test is warranted.
Sample Collection
A small quantity of blood is drawn from your vein and collected in a sealed vial.
Lab Testing
The sample is sent to the lab where chemical process separates and measures the HDL cholesterol levels.
Results
Results are typically available in a few hours to a couple of days depending on the panel.
What are the symptoms that prompt this test?
Adults
- Unexplained fatigue
- High blood pressure
- Chest pain or discomfort
- Shortness of breath
- Obesity or unexplained weight gain
- Diabetes or prediabetes diagnosis
- Family history of heart disease
Children
- Obesity or rapid weight gain
- Family history of high cholesterol or heart disease
- High blood pressure
- Unhealthy eating habits and lack of exercise
What are Normal Ranges for This Test?
Male
- Optimal – 60 mg/dL or higher
- Borderline Low – 40–59 mg/dL
- Low (Increased Risk) – Below 40 mg/dL
Female
- Optimal – 60 mg/dL or higher
- Borderline Low – 50–59 mg/dL
- Low (Increased Risk) – Below 50 mg/dL
Higher HDL levels are generally better, as they are associated with a reduced risk of heart disease.
**The above mentioned range is for information purpose only. Normal levels are dependent on how the test is conducted. Result interpretation should be done by a qualified doctor or healthcare professional.**
What Happens if Test Results Show Abnormal Levels?
If HDL cholesterol levels are low, it may indicate an increased risk of heart disease. The doctor may recommend:
Lifestyle Changes – Such as a heart-healthy diet, regular exercise, quitting smoking and limiting or stopping alcohol intake.
Medications – Such as statins or niacin to improve cholesterol levels.
Further Testing – Such as a full lipid panel or advanced lipid testing to assess overall cardiovascular risk.
If HDL levels are high, it is generally considered beneficial, but the doctor may still evaluate other risk factors for heart disease.
