I am just too tired and lazy to try to search for an article. Ron (I think)I disagree about another ultrasound for dating. The first trimester one is more accurate. I told the CNM she can't have it both ways; if she used the LMP and ultrasound ot assign the EDC of 10/7 based on the LMP (which is what we all think is right), then she can't simply change the EDC assignment to normalize the test. However, if there is evidence that simply using the first trimester scan's EDC is preferrred, then that is another story and we'll have to revamp our EDC calculations.

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.
