With this formula you can calculate the glomerular filtration rate (GFR) using the MDRD study equation:

 

var age = getDateDiff('{DOV}','{DOB}','y');
var eGFR= 186 * Math.pow(({creatinine}/88.4),-1.154) * Math.pow(age,-0.203);
if({sex} == 0) { eGFR = eGFR * 0.742; };
eGFR;

 

In this formula the following variables are used:

  • DOV = date of visit
  • DOB = date of birth
  • Sex = sex
  • Creat = creatinine
