HDL Cholesterol

Understand HDL Cholesterol levels for heart health and protective lipid assessment. Monitor good cholesterol for cardiovascular wellness.

HDL · mg/dL mmol/L · aka HDL-C, HDL CHOL, HIGH DENSITY LIPOPROTEIN, GOOD CHOLESTEROL

What is HDL Cholesterol?

HDL (high-density lipoprotein) cholesterol is known as “good” cholesterol because it transports cholesterol from peripheral tissues back to the liver for disposal or recycling. Higher HDL levels are associated with lower cardiovascular disease risk.

Why is it Tested?

Doctors measure HDL cholesterol to assess cardiovascular protection and overall lipid profile. Unlike other lipid markers, higher HDL levels are protective, making it an important component of cardiovascular risk stratification.

Normal Ranges

Reference ranges differ by gender:

  • Men: 40–60 mg/dL (normal), ≥60 mg/dL (optimal)
  • Women: 50–60 mg/dL (normal), ≥60 mg/dL (optimal)

Low HDL is defined as <40 mg/dL in men and <50 mg/dL in women, indicating increased cardiovascular risk.

Reference ranges vary by authority. Track yours across multiple standards with automatic unit conversions in LabsVault.

What do Abnormal Results Mean?

Abnormal results are not a diagnosis. Always discuss your results with a qualified healthcare provider before making any medical decisions.

Low HDL Cholesterol

Reduced levels may indicate:

  • Increased cardiovascular disease risk
  • Metabolic syndrome or insulin resistance
  • Sedentary lifestyle
  • Smoking
  • Very low-fat diets

High HDL Cholesterol

Elevated levels suggest:

  • Lower cardiovascular disease risk
  • Regular exercise habits
  • Moderate alcohol consumption
  • Genetic factors
  • Some medications

How to Track Over Time

HDL cholesterol responds slowly to lifestyle changes, typically taking months to show improvement from exercise and dietary modifications. Consistent tracking helps assess the effectiveness of interventions aimed at raising HDL and reducing cardiovascular risk.
