preimplantation genetic screening:

see embryo screeningembryo screening,
procedure (see genetic testing) in which a single cell is removed from an embryo two or three days after it has been conceived through in vitro fertilization and tested for genetic abnormalities.

Speakers will focus on subjects such as advances in stimulation protocols, laboratory procedures, preimplantation genetic screening, and stem cell research.
These vary and include extended culture to blastocyst stage, standard morphologic evaluation as well as morphokinetic assessment of embryonic development via time-lapse imaging, and more recently the reintroduction of pre-implantation genetic testing for aneuploidy (PGT-A), formerly known as preimplantation genetic screening (PGS).

The acquisition of CombiMatrix complements Invitae's recent acquisition of another reproductive genetics company, Good Start Genetics, to establish a menu with the breadth and depth needed to provide comprehensive support for women, their partners and clinicians to use genetic information when considering their reproductive health options, from carrier screening to preimplantation genetic screening and diagnosis to newborn diagnostics.
- Researchers from Good Start Genetics, now part of San Francisco, California-based genetic information company Invitae (NYSE: NVTA), are presenting validation data at the American Society for Reproductive Medicine 2017 Scientific Congress and Expo for a novel, NGS-based preimplantation genetic screening technology that accurately identifies certain chromosomal abnormalities potentially missed on other PGS platforms, the company said.

After controlling for hormone levels, number of embryos transferred, diagnosis, age, and preimplantation genetic screening utilization, the investigators found that the difference was largely attributable to an effect in older women; the ongoing pregnancy rate was significantly higher in freeze-all cycles, compared with fresh cycles, among patients over age 35 years (46% vs.
Preimplantation genetic screening and preimplantation genetic diagnosis (PGS/PGD) are genetic tests performed in eight-celled embryos before implantation during in vitro fertilization (IVF) for the detection of genetic abnormalities and sex.

If both partners test positive in a CGT with the same gene mutation, the recommendation is to undertake an IVF procedure and eliminate a genetically effected embryo through preimplantation genetic screening (PGS).
