HDL Cholesterol Formula:
| From: | To: |
HDL (High-Density Lipoprotein) cholesterol is often referred to as "good cholesterol" because it helps remove other forms of cholesterol from your bloodstream. Higher levels of HDL are associated with a lower risk of heart disease.
HDL cholesterol is measured directly through blood tests. The formula is simple:
Where:
Explanation: Unlike calculated values such as LDL cholesterol, HDL is directly measured in standard lipid panel blood tests.
Details: HDL cholesterol plays a crucial role in cardiovascular health by transporting cholesterol from tissues to the liver for excretion. Optimal HDL levels help protect against atherosclerosis and heart disease.
Tips: Enter your measured HDL value from your blood test results in mg/dL. The calculator will display your HDL level as reported.
Q1: What are optimal HDL levels?
A: For men, optimal HDL is 40 mg/dL or higher. For women, optimal HDL is 50 mg/dL or higher. Levels above 60 mg/dL are considered protective against heart disease.
Q2: How can I increase my HDL levels?
A: Regular aerobic exercise, maintaining a healthy weight, consuming healthy fats (like olive oil and avocados), and avoiding trans fats can help increase HDL levels.
Q3: How often should HDL be measured?
A: Adults should have their cholesterol checked every 4-6 years. Those with risk factors for heart disease may need more frequent testing.
Q4: Are there medications that affect HDL levels?
A: Yes, certain medications like niacin, fibrates, and statins can affect HDL levels. Always discuss medication effects with your healthcare provider.
Q5: Is fasting required for HDL testing?
A: Fasting is not required for accurate HDL measurement, though it may be recommended for a complete lipid panel that includes triglycerides.
