Glomerular Filtration Rate Estimate by the MDRD Equation

 
GFR = 170 * SerumCreat-0.999 * Age-0.176 * Sex * Race * BUN-0.170 * Albumin0.318

 
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 m2
 
Decimal Precision  
 
Notes
  • 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.
