This essay presents an anthropological analysis of prenatal diagnosis, a cluster of technologies used for assessing the chromosomal and genetic normalcy of fetuses in utero. An ever-expanding list of these technologies includes ultrasound imaging, amniocentesis, chorionic villus sampling, percutaneousumbilical chord sampling, and other evolving experimental interventions, all backed up by abortion technology for those who receive bad news about the health of their fetuses and choose to end specific pregnancies.
