Re: What day is this? RE: GI biopsies
|From:||Shirley Powell <powell_sa@Mercer.EDU>|
It is not so unheard of, we tried this method many, many, (at least 15) years
ago when I was in the clinical lab. I learned of the method at an NSH meeting
way back then. We also used the Gel Foam method Rhonda eluded to, but abandoned
it later on. When the blue pads came out, the pathologists decided to
discontinue the cucumber method. But it is unique and gets my vote.
