Current standard of care for prenatal genetic testing is used to detect changes in a fetus’s genes before birth and is offered during pregnancy to determine if there is an increased risk that the baby will have a genetic or chromosomal disorder. Prenatal testing may be used to help guide decisions during pregnancy. Next generation sequencing provides high resolution of DNA to measure genetic variation or abnormality if present, offering advantages over existing potentially invasive methods. Studies have demonstrated the feasibility of detecting circulating fetal DNA as a way to perform future prenatal genetic testing.
