Low Density Lipoprotein (LDL) Calculator
Introduction & Importance
Low density lipoprotein (LDL), often referred to as “bad cholesterol,” is a type of lipoproteins that carry cholesterol and triglycerides through your bloodstream to your tissues. Understanding your LDL levels is crucial as high LDL can increase your risk of heart disease and stroke.

Formula & Methodology
The Friedewald equation is used to estimate LDL cholesterol: LDL = Total Cholesterol – HDL – (Triglycerides / 5). However, this calculator uses the Martin-Hopkins equation for better accuracy: LDL = Total Cholesterol – HDL – (Triglycerides / 2.2).
