PGT Meaning and
Definition
-
PGT stands for Preimplantation Genetic Testing. It is a medical procedure used in assisted reproductive technology to screen embryos for specific genetic conditions or abnormalities before they are transferred into the uterus. PGT involves the extraction of one or a few cells from an embryo, typically created through in vitro fertilization (IVF), to analyze its genetic information.
The purpose of PGT is to identify embryos that carry certain genetic disorders or chromosomal abnormalities, allowing couples to select the healthiest embryos for transfer, increasing the chances of a successful pregnancy. PGT can detect inherited genetic diseases, such as cystic fibrosis or sickle cell anemia, as well as chromosomal abnormalities like Down syndrome or Turner syndrome.
The process of PGT typically consists of various laboratory techniques, including amplification of the genetic material present in the cells extracted from the embryo, and subsequent analysis of the DNA. The results of PGT can assist couples in making informed decisions regarding embryo transfer, in order to reduce the risk of passing genetic diseases to their offspring and improve the chances of a successful pregnancy.
PGT is a rapidly advancing field with different techniques being developed, such as PGT-A (aneuploidy screening), PGT-M (monogenic disorder screening), and PGT-SR (structural rearrangement screening). These different types of PGT allow for the identification of different genetic conditions or abnormalities, providing couples with more options and possibilities when it comes to family planning.
