This study demonstrates the many technical limitations of the three testing modalities. Our rates of maternal cell contamination were low, but it is important to note that this is a commonly reported limitation of cytogenetics. Given the similar overall performance of the three testing modalities, providers may choose a method based on individual availability and consideration of limitations as it applies to each clinical scenario. The unexpected high rate of placental mosaicism warrants further investigation.
