Daniel: "Re: Protein creatinine ratio" You're quite right, there is a correlation, and it probably is close enough for clinical use, but I was thinking you were asking if it could be possible to predict exactly - see your question at the bottom. On the other hand what does it tell you in an obstetric population that you can't tell from a simple dipstick? stray "Montgomery, Lynn MD" wrote: > This is why I ask.

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.
