1. What is the TC/HDL Cholesterol Ratio?

The TC/HDL cholesterol ratio is a simple calculation that compares your total cholesterol level to your HDL (good) cholesterol level. This ratio is used to assess cardiovascular risk, with lower ratios indicating better heart health.

2. How Does the Calculator Work?

The calculator uses the Canadian cholesterol ratio formula:

Where:

• \( TC \) — Total cholesterol in mmol/L
• \( HDL \) — HDL cholesterol in mmol/L

Explanation: This simple division provides a ratio that helps assess cardiovascular risk independent of absolute cholesterol values.

3. Importance of Cholesterol Ratio

Details: The TC/HDL ratio is a strong predictor of cardiovascular disease risk. A ratio below 5:1 is considered ideal, while ratios above 5:1 indicate increased risk.

4. Using the Calculator

Tips: Enter both total cholesterol and HDL cholesterol values in mmol/L. 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 ideal. Ratios between 5:1 and 6:1 indicate average risk, while ratios above 6:1 indicate higher cardiovascular risk.

Q2: Why use ratio instead of individual values?
A: The ratio provides a better overall picture of cholesterol balance and cardiovascular risk than looking at individual cholesterol values alone.

Q3: How often should cholesterol be tested?
A: Adults should have cholesterol tested every 4-6 years, or more frequently if risk factors are present or if previous results were abnormal.

Q4: Can lifestyle changes improve the ratio?
A: Yes, regular exercise, healthy diet, weight management, and smoking cessation can improve both HDL levels and the overall cholesterol ratio.

Q5: Are there limitations to this ratio?
A: While useful, the ratio should be interpreted alongside other risk factors and lipid parameters for a complete cardiovascular risk assessment.
