1. What is the TC/HDL-C Ratio?

The TC/HDL-C ratio (Total Cholesterol to HDL Cholesterol ratio) is a calculated value that represents the balance between "bad" and "good" cholesterol in the blood. It's considered a better predictor of cardiovascular risk than either value alone.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( TC \) — Total Cholesterol (mg/dL)
• \( HDL-C \) — HDL Cholesterol (mg/dL)

Explanation: This ratio compares the total amount of cholesterol in your blood to the amount of "good" HDL cholesterol, providing insight into cardiovascular risk.

3. Importance of TC/HDL-C Ratio

Details: A lower ratio indicates a lower risk of heart disease, while a higher ratio suggests increased risk. Generally, a ratio below 5:1 is considered desirable, with optimal being below 3.5:1.

4. Using the Calculator

Tips: Enter both Total Cholesterol and HDL Cholesterol values in mg/dL. Both values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is a healthy TC/HDL-C 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 I check my cholesterol levels?
A: Most adults should have their cholesterol checked every 4-6 years. Those with risk factors may need more frequent testing.

Q3: Can this ratio be improved?
A: Yes, through lifestyle changes like regular exercise, healthy diet, weight management, and if necessary, medication prescribed by your doctor.

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

Q5: Should I fast before cholesterol testing?
A: Traditionally, fasting for 9-12 hours was recommended, but recent guidelines suggest non-fasting tests may be acceptable for initial screening.
