1. What is the TC/HDL Cholesterol Ratio?

The TC/HDL (Total Cholesterol to HDL Cholesterol) ratio is a calculated value that compares the amount of total cholesterol to the amount of high-density lipoprotein (HDL) cholesterol in the blood. It's considered a better predictor of cardiovascular risk than either measurement alone.

2. How Does the Calculator Work?

The calculator uses the simple ratio formula:

Where:

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

Explanation: This ratio provides insight into cardiovascular risk, with lower ratios generally indicating better heart health.

3. Importance of Cholesterol Ratio

Details: The TC/HDL ratio is a significant predictor of cardiovascular disease risk. A higher ratio indicates higher risk, while a lower ratio suggests better cardiovascular health.

4. Using the Calculator

Tips: Enter both total cholesterol and HDL cholesterol values in mmol/L (UK standard units). Both values must be greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is a healthy TC/HDL ratio?
A: Generally, a ratio below 4.0 is considered ideal, between 4.0-5.0 is acceptable, and above 5.0 indicates higher cardiovascular risk.

Q2: Why use the ratio instead of individual values?
A: The ratio provides a more comprehensive view of cholesterol balance and is a better predictor of heart disease risk than individual cholesterol measurements.

Q3: How often should cholesterol levels be checked?
A: Adults should have their cholesterol checked every 4-6 years, or more frequently if they have risk factors for heart disease.

Q4: Can lifestyle changes improve the ratio?
A: Yes, regular exercise, a healthy diet, maintaining a healthy weight, and not smoking can help improve your cholesterol ratio.

Q5: Are there limitations to this calculation?
A: While useful, the ratio should be interpreted alongside other risk factors and in consultation with a healthcare professional.
