1 PGS, preimplantation genetic screening, refers to removing one or more cells from an in vitro fertilization embryo to test for chromosomal normalcy. 2  PGS screens the embryo for normal chromosome number. 3  We can think of PGS as chromosomal disorder screening on IVF embryos.
Preimplantation Genetic Diagnosis (PGD) involves microsurgical removal of one or two blastomeres from a 6 or 8 cell embryo (generally on day 3). Removal of a cell at this point in time does not appear to harm the embryo. Various technologies are then employed to test the embryo for chromosomal abnormalities.
