Good news!
"Using whole-genome sequencing, they detected fetal genetic abnormalities such as trisomies, the presence of an extra chromosome, with high accuracy. This technique could have the potential to replace more invasive tests such as amniocentesis or chorionic villi sampling, and it appears to be more accurate than a similar procedure that tests cell-free DNA in the mother’s bloodstream."
Circulating Fetal Cells Sequenced for Prenatal Testing Study | The Scientist Magazine®: Trophoblasts, collected from the mother during a blood draw, can determine fetal genetic abnormalities currently diagnosed through amniocentesis or chorionic villi sampling.
