Cardiovascular

HDL cholesterol levels: what do they tell you about your vascular protection?

HDL cholesterol is a cornerstone of cardiovascular health screening. Regular monitoring helps assess your heart's protective factors and guide preventive action.

Reference Ranges

Male
mmol/l
Low > 1 Normal
Female
mmol/l
Low > 1.2 Normal

Reference ranges may vary between laboratories. When you order a test, a BIG-registered doctor assesses your personal results in context. For treatment decisions, discuss your results with your GP.

What It Measures

This test measures the amount of cholesterol carried by HDL particles in your blood. HDL acts as a scavenger, removing cholesterol from arterial walls.

Why It Matters

HDL cholesterol is a key component of cardiovascular risk assessment. Low HDL may be associated with increased heart disease risk, while healthy levels support arterial protection. Consult your healthcare provider for personalised guidance.

When to Test

HDL testing is part of a standard lipid panel and is recommended for routine cardiovascular screening. Testing frequency depends on your age and risk factors.

Symptoms

Low Levels

Low HDL does not typically cause symptoms but increases cardiovascular risk over time. It may be associated with metabolic syndrome, physical inactivity, and smoking.

High Levels

High HDL is generally protective. Very high levels are usually not a concern but should be discussed with your healthcare provider in context of your overall lipid profile.

Recommendations

Male

If Low

Low HDL increases cardiovascular risk. Consider more exercise and healthy fats.

If High

High HDL is protective and beneficial for heart health.

Female

If Low

Low HDL increases cardiovascular risk. Consider more exercise and healthy fats.

If High

High HDL is protective and beneficial for heart health.

Lifestyle Tips

Regular aerobic exercise is the most effective way to raise HDL. Eating healthy fats (olive oil, nuts, avocados), maintaining a healthy weight, and avoiding smoking also support HDL levels.

Frequently Asked Questions

Why is HDL called "good" cholesterol?
HDL helps remove excess cholesterol from your arteries and transport it to the liver for disposal, reducing plaque build-up and cardiovascular risk.
What is the best way to raise HDL?
Regular aerobic exercise is the most effective method. A diet rich in healthy fats, moderate alcohol intake, and not smoking also help.
Can HDL be too high?
Extremely high HDL is rare and generally not a concern. However, the quality and function of HDL particles matter alongside the quantity. Discuss your levels with your healthcare provider.
