1. What is Total Cholesterol/HDL Ratio?

The Total Cholesterol to HDL Ratio is a calculated value that compares the amount of total cholesterol to high-density lipoprotein (HDL) cholesterol in the blood. This ratio is used as an indicator of cardiovascular risk.

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 provides insight into the balance between "bad" and "good" cholesterol in the bloodstream.

3. Importance of TC/HDL Ratio

Details: A lower ratio indicates a lower risk of heart disease, while a higher ratio suggests increased cardiovascular risk. This ratio is considered by many experts to be a better predictor of heart disease risk than total cholesterol alone.

4. Using the Calculator

Tips: Enter total cholesterol and HDL cholesterol values in mg/dL. 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: How often should this ratio be checked?
A: Adults should have their cholesterol levels checked every 4-6 years, or more frequently if risk factors are present.

Q3: Can this ratio be improved?
A: Yes, through lifestyle changes such as regular exercise, healthy diet, maintaining healthy weight, and if necessary, medication.

Q4: Are there limitations to this ratio?
A: While useful, it doesn't account for other risk factors like family history, smoking, blood pressure, or other lipid components.

Q5: Should this replace other cholesterol measurements?
A: No, it should be used in conjunction with other lipid measurements and risk assessment tools for comprehensive evaluation.
