Total Cholesterol to HDL Ratio
Cholesterol ratios provide a more comprehensive view of cardiovascular health than looking at individual cholesterol numbers alone. The most commonly used ratio is the total cholesterol to HDL ratio, which helps assess heart disease risk.
This is the overall amount of cholesterol in your blood, including both HDL and LDL. Desirable total cholesterol is less than 200 mg/dL.
Often called "good" cholesterol, HDL helps remove other forms of cholesterol from your bloodstream. Higher levels are better:
Known as "bad" cholesterol, LDL contributes to plaque buildup in arteries. Target levels:
| Risk Level | Men | Women |
|---|---|---|
| Optimal (Low Risk) | Below 3.5 | Below 3.5 |
| Good | 3.5 - 5.0 | 3.5 - 4.4 |
| Moderate Risk | 5.0 - 9.6 | 4.4 - 7.1 |
| High Risk | Above 9.6 | Above 7.1 |
This ratio is another important indicator:
Cholesterol ratios can be more predictive of heart disease risk than individual numbers because they consider the balance between protective HDL and harmful LDL cholesterol. For example:

Many other factors contribute to heart disease risk, including age, blood pressure, smoking status, diabetes, and family history. Always consult with a healthcare provider for proper evaluation of your cholesterol levels and cardiovascular health.
