PGS and PGD are types of genetic tests used during in vitro fertilization (IVF) to test an embryo for extra or missing chromosomes and/or inherited diseases, like Cystic Fibrosis. The goal of both PGS and PGD testing is to find out which embryos are most likely to result in a healthy pregnancy. [LESS]
Both PGS and PGD are done on an embryo biopsy as part of an IVF cycle. PGS screens embryos for whole extra or missing chromosomes. PGD tests embryos for a specific genetic disease or small extra or missing pieces of chromosomes.
PGS or PGD tests are done after fertilization by removing a single cell or multiple cells from a developing embryo for testing. The biopsy is performed by an embryologist at an IVF center. It can be done either 3 days or 5 days after fertilization. In either case, the biopsy samples are sent to Natera for testing. The embryos remain at the IVF center. Once results are given to your IVF doctor, you and your doctor decide which embryos to transfer.#natera, #PGS. #PGD, #infertilitytestReturn to Blog
