1. What is the HDL vs LDL Ratio?

The HDL vs LDL Ratio is a simple calculation that compares the levels of HDL cholesterol (the "good" cholesterol) to LDL cholesterol (the "bad" cholesterol) in the blood. This ratio provides insight into cardiovascular health risk assessment.

2. How Does the Calculator Work?

The calculator uses the HDL vs LDL Ratio formula:

Where:

• \( HDL-C \) — HDL cholesterol (mg/dL or mmol/L)
• \( LDL-C \) — LDL cholesterol (mg/dL or mmol/L, same unit as HDL-C)

Explanation: The ratio is calculated by dividing the HDL cholesterol value by the LDL cholesterol value, providing a dimensionless number that indicates the balance between protective and harmful cholesterol.

3. Importance of HDL vs LDL Ratio

Details: A higher ratio indicates better cardiovascular health, as it suggests more protective HDL relative to harmful LDL. This ratio is used alongside other lipid parameters for comprehensive cardiovascular risk assessment.

4. Using the Calculator

Tips: Enter both HDL-C and LDL-C values in the same units (mg/dL or mmol/L). Both values must be greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is a good HDL vs LDL ratio?
A: Generally, a ratio above 0.3-0.4 is considered favorable, with higher values indicating better cardiovascular health. However, optimal ratios may vary based on individual risk factors.

Q2: How does this ratio compare to total cholesterol/HDL ratio?
A: While total cholesterol/HDL ratio is more commonly used, the HDL/LDL ratio provides a more specific assessment of the balance between protective and harmful cholesterol fractions.

Q3: Can this ratio be used alone for risk assessment?
A: No, this ratio should be used in conjunction with other lipid parameters and risk factors for comprehensive cardiovascular risk assessment.

Q4: What are typical HDL and LDL values?
A: Typically, HDL >40 mg/dL (men) or >50 mg/dL (women) is desirable, while LDL <100 mg/dL is optimal for most adults.

Q5: How often should cholesterol levels be checked?
A: Adults should have lipid profiles checked every 4-6 years, or more frequently if risk factors are present or values are abnormal.
