The reduction in amniocentesis for AMA has been offset by an increasing number of amniocenteses
for fetal anomalies, resulting in a levelling off in overall numbers of amniocenteses
Using a mathematical model and historical data, we found that the maternal serum screen had greater sensitivity and lower false-positive rates in detecting Down syndrome, compared with basing risk on age and conducting amniocenteses
a community hospital at which perinatologists performed amniocenteses
much more frequently than did ob.
This finding, based on a review of almost 4,500 amniocenteses
done on fetuses aged 11-20 weeks in Alberta, Canada, during 1994-1997, is the largest study so far to examine the impact of early second-trimester amniocentesis on foot malformations, said Dr.
A total of 642 amniocenteses
were undertaken over the period.
This testing will ultimately decrease the number of amniocenteses
, and thus reduce the number of miscarriages caused by amniocenteses
