How It Works
How It Works
This calculator estimates your LDL ("bad") cholesterol using the Friedewald Equation. It uses three common cholesterol test results: Total Cholesterol, HDL ("good") Cholesterol, and Triglycerides.
The formula subtracts HDL and a portion of your triglycerides (Triglycerides divided by 5) from your Total Cholesterol. The final number is rounded to the nearest whole number to give your estimated LDL level in mg/dL.
- Start with your Total Cholesterol value
- Subtract your HDL (good) cholesterol
- Divide Triglycerides by 5 and subtract that number
- Round the result to the nearest whole number
- The final number is your Estimated LDL Cholesterol (mg/dL)
Understanding the Results
Your result shows an estimate of your LDL cholesterol level. LDL is often called "bad" cholesterol because higher levels can increase the risk of heart disease.
In general, lower LDL levels are considered better for heart health. Your healthcare provider can help you understand what range is appropriate for you based on your overall health and risk factors.
- Lower LDL levels are generally better for heart health
- High LDL may increase the risk of heart disease
- Results are estimates based on standard lab values
- This formula works best when triglycerides are under 400 mg/dL
- Always review your results with a healthcare professional
