The Friedewald equation is valid when serum triglycerides are below 400 mg/dL (4.5 mmol/L). For higher triglycerides, direct LDL laboratory measurement is required.

Calculation Methodology

Friedewald Equation: LDL-C (mg/dL) = Total Cholesterol - HDL-C - (Triglycerides / 5). Non-HDL Cholesterol = Total Cholesterol - HDL-C. Chol/HDL Ratio = Total Cholesterol / HDL-C.

Frequently Asked Questions

Optimal is below 100 mg/dL (under 70 mg/dL for high-risk cardiac patients), borderline high is 130-159 mg/dL, and very high is ≥190 mg/dL.
