Hi Julee,
Meditech has a KB article (18534) about Estimated GFR.
To help you/your users test to be sure the calculation is correct, here
is a reference range chart:
http://www.postgradmed.com/issues/2001/12_01/manjunath.htm

I created a LAB Calc that looks like this:
Mnemonic  EGFR Active? Y   Description ESTIMATED GLOMERULAR FILT RATE
Type  POST

Target Test                         Trigger Tests

                                                              CREAT
Ask Recalc?  N

Edit?
   [f lsp age]^AGE,
   CREAT^CRE,
   186.3*[f fcn power](CRE,"-1.154")*[f fcn power](AGE,"-0.203")^RES,
   IF{L([f pt age])>3 [f lres nop];
    (([f pt sex]="F")&([f pt race]="B")) RES*0.742*1.210;
    [f pt sex]="F" RES*0.742;
    [f pt race]="B" RES*1.212;RES};

Then, I created a LAB Test that looks like this:
Print Number  100.1750

                              60-116

Add the above LAB Test to the profile of the BMP and CMP tests.


Hope this helps.

Can anyone give me some info on the GFR calc you have built in Meditech.
I have a Dr. that wants us to start using this and I am trying to gather
info on what I need to do in Meditech to get this built.  Thank you in
advance.
