TC/HDL Ratio Formula:
| From: | To: |
The TC/HDL (Total Cholesterol to HDL Cholesterol) ratio is used in UK guidelines for cardiovascular risk assessment. It provides a more comprehensive view of cardiovascular risk than total cholesterol alone by considering the balance between "bad" and "good" cholesterol.
The calculator uses the simple ratio formula:
Where:
Explanation: The ratio compares the total amount of cholesterol in your blood (including both LDL and HDL) to the amount of "good" HDL cholesterol. A lower ratio indicates better cardiovascular health.
Details: The TC/HDL ratio is a strong predictor of cardiovascular disease risk. UK guidelines use this ratio as part of comprehensive cardiovascular risk assessment to guide treatment decisions and lifestyle recommendations.
Tips: Enter total cholesterol and HDL cholesterol values in mmol/L. Both values must be valid (greater than 0). The calculator will compute the ratio instantly.
Q1: What is a good TC/HDL ratio?
A: Generally, a ratio below 4 is considered ideal. Ratios above 5 indicate increased cardiovascular risk, while ratios above 6 indicate high risk.
Q2: Why is the TC/HDL ratio important?
A: It provides a better assessment of cardiovascular risk than total cholesterol alone because it considers the protective effect of HDL cholesterol.
Q3: How often should I check my cholesterol ratio?
A: Adults should have their cholesterol checked every 4-6 years, or more frequently if you have risk factors for heart disease.
Q4: Can I improve my TC/HDL ratio?
A: Yes, through lifestyle changes such as regular exercise, healthy diet (reducing saturated fats), maintaining healthy weight, and not smoking.
Q5: Is this calculator specific to UK guidelines?
A: Yes, this calculator follows UK cardiovascular risk assessment guidelines which commonly use the TC/HDL ratio.
