1. What is TC/HDL Ratio?

The TC/HDL ratio is a calculated value that compares your total cholesterol to your HDL (high-density lipoprotein) cholesterol. This ratio is used to assess cardiovascular risk, with a lower ratio indicating better heart health.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

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

Interpretation: A ratio below 4.5 is considered optimal, while higher values may indicate increased cardiovascular risk.

3. Importance of TC/HDL Ratio

Details: The TC/HDL ratio is a stronger predictor of cardiovascular disease than total cholesterol or LDL cholesterol alone. It provides a better assessment of cholesterol balance and heart disease risk.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What is the ideal TC/HDL ratio?
A: A ratio below 4.5 is considered optimal. The lower the ratio, the better your cardiovascular risk profile.

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 (especially increasing omega-3 fatty acids), maintaining a healthy weight, and quitting smoking.

Q4: Are there limitations to this ratio?
A: While useful, the TC/HDL ratio should be considered alongside other risk factors such as blood pressure, diabetes, smoking status, and family history.

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