Prenatal DNA testing can be performed using a CVS sample or an amniotic fluid sample. If you are interested in proceeding with prenatal testing, the first step is to arrange an appointment for amniocentesis or CVS with your physician/obstetrician. Once the appointment is confirmed, please let us know and we will help you to initiate a file and send the collection kit directly to your physician. The turnaround time is 3 to 5 business days from the date that we receive the samples. If you are unable to have a prenatal sample collected, please note that DNA testing can be performed on the day of birth using a mouth swab kit.
