1. What is HDL?

HDL (High-Density Lipoprotein) 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.

2. How is HDL Measured?

HDL is measured through direct laboratory testing of blood samples. The measurement is expressed in milligrams per deciliter (mg/dL).

Explanation: Unlike calculated values, HDL is directly measured through chemical methods in laboratory settings, providing an accurate assessment of high-density lipoprotein levels in the blood.

3. Importance of HDL Levels

Details: Maintaining healthy HDL levels is crucial for cardiovascular health. Optimal HDL levels help transport cholesterol from arteries to the liver for removal, reducing plaque buildup and lowering heart disease risk.

4. Using the Calculator

Tips: Enter your laboratory-measured HDL value in mg/dL. The calculator confirms your input value since HDL is directly measured rather than calculated.

5. Frequently Asked Questions (FAQ)

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 exercise, healthy fats (olive oil, avocados, nuts), quitting smoking, and moderate alcohol consumption can help raise HDL levels.

Q3: When should HDL be measured?
A: HDL should be measured as part of a fasting lipid profile. Fasting for 9-12 hours before the test provides the most accurate results.

Q4: Are there limitations to HDL measurement?
A: While direct measurement is accurate, HDL levels can be affected by recent illness, medications, and lifestyle factors. Repeat testing may be needed for confirmation.

Q5: Why is HDL called "good cholesterol"?
A: HDL particles remove cholesterol from arteries and transport it back to the liver for processing or removal, helping to prevent arterial plaque buildup.
