Glomerular Filtration Rate Estimate by the MDRD Equation (SI units)

 
Input
 
Serum Creat  
Age  
Sex Female (0.762)

Male (1)
Race Black (1.18)

Non-Black (1)
BUN  
Albumin  

 
Result
 
 
GFR   mL/min/1.73 m^2
 
Decimal Precision  
 
Notes
  • In this calculator, mcg is the abbreviation for micrograms.

 
Equations used
 
GFR = 169.98 * (SerumCreat/88.4)-0.999 * Age-0.176 * Sex * Race * (BUN/0.357)-0.170 * (Albumin/10)0.318

 
Calculation Details and Variables
  • Equation parameters such as Sex, have two or more discrete values that may be used in the calculation. The numbers in the parentheses, e.g. (0.762), represent the values that will be used.
