Despite how large the office is, that's not a lot of practice for their embryologists. PGS testing is mainly performed to rule the possibility of embryos carrying aneuploid chromosomes, thus can only detect numerical changes in chromosome number. That’s right. Preimplantation Genetic Diagnosis (PGD) and Preimplantation Genetic Screening (PGS) are genetic tests combined with the IVF process to diagnose an embryo prior to embryo transfer for an abnormal number of chromosomes or genetic mutations.
