Calculator: Friedewald Equation for Low Density Lipoprotein (LDL-C) (SI units)*

 
Input
 
Total cholesterol  
HDL-C  
Triglyceride  

 
Result
 
Important: Inputs must be complete to perform calculation.

 
 
LDL-C  
 
Decimal precision  

 
 

 
Notes
  • This calculation is not valid when the Triglyceride level is ≥4.5 mmol/L.
  • HDL-C: high-density lipoprotein cholesterol; LDL-C: low-density lipoprotein cholesterol.
  • * This calculator uses SI units (Système international d'unités) as the default for inputs. Do not use this calculator if you are using conventional units (also known as US units and gravimetric units); please refer instead to the conventional units version of this calculator.

 
Equations used
 
LDL-C = Total cholesterol - (Triglyceride / 2.2) - HDL-C

 

 
Only digits 0 to 9 and a single decimal point (".") are acceptable as numeric inputs. Attempted input of other characters into a numeric field may lead to an incorrect result.
