We have a legal constraint (GBEA and best practices) to make sure that the appropriate alert is issued for severe and urgent cases. In this paper, we present a study of the performances of data transfer tools, such as the comparison between regular phone and up to date available means like in line printers and network terminals.

Method: On the basis of a prospective study of second-trimester maternal serum screening, we studied the distribution of alpha-fetoprotein (AFP) and free ss hCG in 3043 twin pregnancies with known outcome. There were 1561 dichorionic and 244 monochorionic pregnancies.
Objectives: In France, maternal serum marker screening is governed by specific legislation. We conducted a study of the countrywide trisomy 21 screening based on second trimester maternal serum markers.
Methods: We reviewed the medical records of 854,902 patients prospectively screened for second trimester maternal serum markers in the 60 authorized laboratories over the two-year period 1997-1998.
