1. What is the TC/HDL Ratio?

The TC/HDL ratio is a calculated value that compares your total cholesterol level to your HDL (high-density lipoprotein) cholesterol level. This ratio is considered a better predictor of heart disease risk than total cholesterol alone.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

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

Explanation: The ratio is calculated by dividing total cholesterol by HDL cholesterol. A lower ratio indicates a lower risk of heart disease.

3. Importance of TC/HDL Ratio

Details: The TC/HDL ratio is an important cardiovascular risk marker. It provides insight into the balance between "bad" cholesterol (LDL and other non-HDL cholesterol) and "good" cholesterol (HDL).

4. Using the Calculator

Tips: Enter total cholesterol and HDL cholesterol values in mmol/L. Both values must be valid (greater than 0).

5. Frequently Asked Questions (FAQ)

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

Q2: Why is TC/HDL ratio important?
A: It provides a better assessment of heart disease risk than total cholesterol alone because it considers the protective effect of HDL cholesterol.

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

Q4: Can I improve my TC/HDL ratio?
A: Yes, through lifestyle changes like regular exercise, healthy diet (rich in fruits, vegetables, and whole grains), maintaining a healthy weight, and not smoking.

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