Interesting. I just had my first pt with anti-M; she's now 20 weeks. There is (I believe) only one case report of an affected baby of a mother with anti-M. In general anti-M is of no clinical significance; titers are probably not necessary. I am, however, doing them q month just out of curiosity (they have been 1:8 since her first visit at 8 weeks). If she inceased by 2 dilutions, I think I'd get MCA dopplers, mostly out of academic curiosity.

The same week I got a new pt with anti Fya. From what I learned in residency "Kell kills, Lewis lives, Duffy dies." Apparently however, this is wrong, too, and Duffy isn't a big deal either. I'm doing the same with her; she's still too low to titrate.

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.
