A biopsy, or removal of one or two cells, from an early IVF embryo for preimplantation genetic diagnosis after in vitro fertilisation.
                                                            
                                                     
                        
                                                
                        
                        
                            Embryo biopsy, also known as pre-implantation genetic diagnosis, is an experimental test for genetic abnormalities in embryos before they are implanted using IVF (in vitro fertilisation).
