Preimplantation Genetic Testing
Preimplantation genetic testing (PGT) is a way of safeguarding against genetic diseases or disorders. Intended parents can prevent a pregnancy affected by a genetic condition or chromosomal disorder. This advanced testing can identify specific embryos that are free of abnormalities before they are transferred into a woman’s uterus (womb) by in vitro fertilization (IVF).
PGT can also assist intended parents interested in having a child who is a healthy bone marrow or blood match to another family member. Technology makes it possible to select embryos that match HLAs (human leukocyte antigen), the proteins in white blood cells that are matched in order to do a blood or bone marrow transplant.
PGT can test for and potentially prevent many diseases and genetic disorders, including:
Because of these limitations, prenatal testing later in pregnancy is strongly advised in order to confirm the diagnosis and review the number and structure of all the chromosomes.
Also based on cell development, some PGT testing may yield no diagnosis, partial diagnosis or even sometimes result in no normal embryos for embryo transfer. The likelihood that this will happen is often dependent on your age.
