Glomerular Filtration Rate Estimate by the MDRD Equation

 

Input
 

Serum Creat		gm/L gm/dL mg% mg/dL mg/mL
Age		mo yr
Sex	Female (0.762)
	Male (1)
Race	Black (1.18)
	Non-Black (1)
BUN		gm/L gm/dL mg% mg/dL mg/mL
Albumin		gm/L gm/dL mg% mg/dL mg/mL

 

Result
 

GFR		mL/min/1.73 m2
Decimal Precision   0 1 2 3

 

 
Equations used
 

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

 

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.
