HDL (high-density lipoprotein) is called 'good' cholesterol because it carries cholesterol away from the arteries to the liver for removal.
- Normal range (adults)
- Men 40 or above mg/dL (1.03 or above mmol/L) · Women 50 or above mg/dL (1.29 or above mmol/L)
- Sample
- Blood
- Fasting
- Not usually needed
- Also called
- HDL Cholesterol, Serum HDL cholesterol level, HDL, High Density Lipoprotein, HDL-C, Good Cholesterol, Serum HDL
HDL Cholesterol normal range
| Group | mg/dLConventional units: US, South Asia | mmol/LSI units: UK, Europe, Australia, international |
|---|---|---|
| Men | 40 or above | 1.03 or above |
| Women | 50 or above | 1.29 or above |
Your report may use either unit system; labs in the Gulf often print both. Ranges also vary slightly between laboratories, so the range printed on your own report is the one to go by.
Why is the HDL Cholesterol test done?
It is part of the lipid profile. Low HDL is an independent risk factor for heart disease.
What does a high HDL Cholesterol level mean?
Higher HDL is generally protective. Extremely high levels (above about 100 mg/dL) are not necessarily extra-protective and may be inherited.
Common causes
- Regular exercise
- Healthy weight
- Genetics
- Moderate alcohol intake (not a reason to start drinking)
Diet and lifestyle tips
- Keep up your healthy habits
- No action needed unless your doctor advises
What does a low HDL Cholesterol level mean?
Low HDL means less cholesterol is cleared from your arteries, which raises heart risk. It often goes with high triglycerides and insulin resistance.
Common causes
- Lack of exercise
- Overweight, especially around the waist
- Smoking
- Diet high in sugar and refined carbohydrates
- Type 2 diabetes and insulin resistance
- Genetics
Diet and lifestyle tips
- Exercise regularly: brisk walking, cycling or swimming most days
- Lose excess weight, especially belly fat
- Stop smoking
- Use healthy fats: olive oil, nuts, avocado, oily fish
- Cut sugar, white bread, white rice and sweet drinks
When should you see a doctor?
Low HDL adds to your overall heart risk; review it with your doctor together with your LDL, triglycerides, blood pressure and blood sugar.
