The triple screen gives a result as a 1/X chance of having Down'sSyndrome. If you rec. amniocentesis and all patients accept it when the risk is greater than 1/365, you will diagnose about 2/3 fo the Down's syndrome patients in your population. The AFP alone will pick up about 50% and Maternal age alone will be around 25%. The triple screen should never be reported to the patient as normal or abnormal. They should be told the risk is 1 in ten thousand or the risk is one in ten. -- @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ R.

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.
