When you introduce the words "reagent quality" it means that a chemical manufacturer has done specific tests to assure that the water complies with such designation. Deionized water is usable for solutions preparations but the issue resides in the deionizer that has to be tested as to its performance.
No "small laboratory" has the  conditions required to perform microbiology cultures, nor it is really necessary to do under normal working histology conditions.
If these are new CAP requirements it seems to me that CAP is going beyond reasonable requirements.

   In  regards to CAP's Lab General Checklist questions regardin= g water
   quality:

   




   


   Is  deionized  water  consid=  ered  CLRW (Clinical Laboratory Reagent
   Water)?

   


   Is  water  testin=  g  necessary  for  a Histology Lab?  If so, how do
   small labs test f= or resisitivity and perform microbiology cultures?

   




   


   Would  anyone  be  willing to share their procedure for Water Quality   for a small, private pathology lab?

   




   


   Thank= s,
