About LDL Calculation

LDL is calculated using the Friedewald formula: LDL = Total Cholesterol – HDL – (Triglycerides/5). Note: This formula is less accurate when triglycerides exceed 400 mg/dL.

Step 2: Additional Factors

Risk Factors

Diabetes, smoking, hypertension, and family history of heart disease increase your cardiovascular risk. Lower LDL targets may be recommended.

Cholesterol Breakdown

Friedewald Formula

LDL = Total Cholesterol – HDL – (Triglycerides/5)

Example: LDL = 200 – 50 – (150/5) = 200 – 50 – 30 = 120 mg/dL

Alternative: LDL = Total Cholesterol – HDL – (Triglycerides × 0.2)
