Cholesterol Calculations
Friedewald Equation for LDL
LDL = Total Cholesterol - HDL - (Triglycerides / 5)
This estimate is accurate when triglycerides are below 400 mg/dL.
Cholesterol Ratio
Ratio = Total Cholesterol / HDL
A ratio below 5 is desirable. Below 3.5 is optimal.
Target Ranges
Example Calculation
Total cholesterol 200, HDL 55, triglycerides 150 mg/dL.
- 01LDL = 200 - 55 - (150 / 5) = 200 - 55 - 30 = 115 mg/dL
- 02Ratio = 200 / 55 = 3.6
- 03Non-HDL = 200 - 55 = 145 mg/dL
