Abstract
The number of viable amniotic fluid cells in the aliquot obtained at amniocentesis is an important determinant of the success of subsequent cell culture. However, cell concentration and viability are highly variable, even in samples of equivalent gestational age. We studied the effect of prescribed maternal position change or spontaneous fetal movement on the concentration, viability, and subsequent harvest time of amniotic fluid cells removed at genetic amniocentesis. Samples from 108 patients at 15 to 22 weeks' gestation were evaluated. We did not find a relationship between this type of maternal or fetal movement and the retrieval of amniotic fluid cells.
