About 3 years ago, our lab director announced that they were going to stop reporting bands for these reasons. I thought she was crazy, so I went to the library and poked around and found that she was exactly right. It was very strange and unsettling at first not to have the bands reported, but now I find that I don't miss it at all. I didn't keep either the articles I read or the references to them, but I recall that this was a very strong consensus among pathologists, not just a minority or idiosyncratic opinion. -- --------------------------------------------------------------------------- --------------------------------------------------------------------------- Bob Woolley --------------------------------------------------------------------------- St. Paul, Minnesota "Tyranny is always better organized than freedom." -- Thomas Paine Next message: art fougner, md: "Re: Jehovah's witnesses" Previous message: DoctorJoe@aol.com: "Re: Jehovah's witnesses" Maybe in reply to: Ricardo Savaris: "Band neutrophils values in Pregnancy"

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
