The couple must undergo IVF procedures to generate embryos in vitro. The embryos can be biopsied at either the zygote, cleavage or blastocyst stage. Preimplantation genetic screening uses the same technology to screen for chromosome abnormalities in embryos from patients undergoing IVF procedures as a method of embryo selection. Fluorescence in-situ hybridization was originally used for chromosome analysis, but has now been replaced by array comparative genomic hybridization or next generation sequencing. For the diagnosis of single gene defects, polymerase chain reaction is used and has become highly developed; however, single nucleotide polymorphism arrays for karyomapping have recently been introduced. A partnership between IVF laboratories and diagnostic centres is required to carry out PGD and preimplantation genetic screening. Accreditation of PGD diagnostic laboratories is important. Accreditation gives IVF centres an assurance that the diagnostic tests conform to specified standards. ISO 15189 is an international laboratory standard specific for medical laboratories. A requirement for accreditation is to participate in external quality assessment schemes. date: 2016-03 date_type: published publisher: ELSEVIER SCI LTD official_url: http://dx.doi.org/10.1016/j.rbmo.2015.11.020 oa_status: green full_text_type: other language: eng primo: open primo_central: open_green article_type_text: Article verified: verified_manual elements_id: 1103114 doi: 10.1016/j.rbmo.2015.11.020 lyricists_name: Dhanjal, Seema lyricists_name: Harper, Joyce lyricists_name: Sen Gupta, Sioban lyricists_id: SDHAN57 lyricists_id: JHARP65 lyricists_id: SBSEN97 full_text_status: public publication: Reproductive BioMedicine Online volume: 32 number: 3 pagerange: 263-270 pages: 8 issn: 1472-6483 citation: SenGupta, SB; Dhanjal, S; Harper, JC; (2016) Quality control standards in PGD and PGS.
