1. What is TC/HDL Cholesterol Ratio?

The TC/HDL (Total Cholesterol to HDL Cholesterol) ratio is a calculated value that compares your total cholesterol level to your HDL ("good") cholesterol level. This ratio is considered a better predictor of heart disease risk than either measurement alone.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( TC \) — Total Cholesterol (mg/dL)
• \( HDL \) — HDL Cholesterol (mg/dL)

Explanation: The ratio is calculated by dividing your total cholesterol value by your HDL cholesterol value.

3. Importance of TC/HDL Ratio

Details: A lower ratio indicates a lower risk of heart disease. Generally, a ratio below 5:1 is considered good, with the ideal ratio being below 3.5:1. This ratio provides a more comprehensive view of cardiovascular risk than looking at total cholesterol alone.

4. Using the Calculator

Tips: Enter your total cholesterol and HDL cholesterol values in mg/dL. Both values must be greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is a healthy TC/HDL ratio?
A: A ratio below 5:1 is considered good, with the ideal ratio being below 3.5:1. Higher ratios indicate increased cardiovascular risk.

Q2: How often should I check my cholesterol levels?
A: Adults should have their cholesterol checked every 4-6 years, or more frequently if you have risk factors for heart disease.

Q3: Can I improve my TC/HDL ratio?
A: Yes, through lifestyle changes such as regular exercise, healthy diet (rich in fruits, vegetables, and whole grains), maintaining a healthy weight, and quitting smoking.

Q4: Are there limitations to this ratio?
A: While useful, the ratio should be interpreted alongside other risk factors and lipid measurements for a complete cardiovascular risk assessment.

Q5: Should fasting be required for cholesterol tests?
A: Traditionally, fasting was required, but recent guidelines suggest non-fasting measurements may be acceptable for initial screening in many cases.
