Total Cholesterol/HDL Ratio Formula:
From: | To: |
The Total Cholesterol to HDL Ratio is a calculated value that compares your total cholesterol level to your HDL (high-density lipoprotein) cholesterol level. This ratio is used by healthcare providers to assess cardiovascular risk, with lower ratios indicating better heart health.
The calculator uses a simple formula:
Where:
Explanation: This ratio provides a more comprehensive view of heart disease risk than looking at total cholesterol alone, as it considers the protective effect of HDL cholesterol.
Details: The Total Cholesterol/HDL Ratio is a significant predictor of cardiovascular disease risk. A higher ratio indicates a higher risk of heart disease, while a lower ratio suggests better cardiovascular health. Generally, a ratio below 5:1 is considered good, with the ideal ratio being below 3.5:1.
Tips: Enter your total cholesterol and HDL cholesterol values in mg/dL. Both values must be greater than zero. The calculator will compute your cholesterol ratio, which is a unitless value.
Q1: What is a healthy cholesterol ratio?
A: A ratio of 5:1 is considered average risk, 3.5:1 is considered ideal, and ratios above 5:1 indicate increased cardiovascular risk.
Q2: Why is the cholesterol ratio important?
A: The ratio provides a better assessment of heart disease risk than total cholesterol alone because it accounts for the protective effect of HDL cholesterol.
Q3: How can I improve my cholesterol ratio?
A: You can improve your ratio by increasing HDL through exercise, healthy fats, and quitting smoking, or by lowering total cholesterol through diet and medication.
Q4: Should I fast before cholesterol testing?
A: For the most accurate results, a 9-12 hour fast is typically recommended before cholesterol testing, though some modern tests don't require fasting.
Q5: How often should cholesterol be checked?
A: Adults should have their cholesterol checked every 4-6 years, or more frequently if you have risk factors for heart disease or a history of high cholesterol.
