Description

Live cells (skin biopsy, amniotic fluid, chorionic villi, fetal tissue, products of conception) obtained for constitutional genetic testing are routed to the UWMC - Montlake DLMP Cytogenetic and Genomics Laboratories for cell culture. The cell culture is then sent elsewhere for specific molecular genetic testing.
