TC/HDL Ratio Formula:
| From: | To: |
The TC/HDL ratio (Total Cholesterol to HDL Cholesterol Ratio) is a calculated value that compares the amount of total cholesterol to the amount of HDL (good) cholesterol in the blood. This ratio is used as an indicator of cardiovascular risk.
The calculator uses the simple formula:
Where:
Explanation: The ratio provides insight into the balance between "bad" cholesterol (LDL and other non-HDL cholesterol) and "good" cholesterol (HDL).
Details: A lower TC/HDL ratio indicates a lower risk of cardiovascular disease, while a higher ratio suggests increased risk. This ratio is considered by many experts to be a better predictor of heart disease risk than total cholesterol alone.
Tips: Enter both total cholesterol and HDL cholesterol values in mg/dL. Both values must be greater than zero for accurate calculation.
Q1: What is a healthy 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 does this ratio compare to other cholesterol measurements?
A: The TC/HDL ratio provides a more comprehensive view of cholesterol balance than looking at total cholesterol or LDL alone, as it considers the protective effect of HDL cholesterol.
Q3: Can this ratio be used for treatment decisions?
A: While the ratio is a useful risk assessment tool, treatment decisions should be based on comprehensive lipid profile and individual risk factors under medical guidance.
Q4: Does the ratio have limitations?
A: Like all cholesterol measurements, the ratio should be interpreted in the context of other risk factors and may be affected by recent dietary changes, medications, or acute illness.
Q5: How often should cholesterol levels be checked?
A: Adults should have their cholesterol checked every 4-6 years, or more frequently if they have risk factors for heart disease or are on cholesterol-lowering treatment.
