Clinical specimen: Day 5 embryo biopsy in special tube provided by Cordon Genomics. 

TEST DESCRIPTION:

Normal embryos carry 23 pairs of chromosomes. An imbalance in chromosome numbers, i.e. the presence of extra or missing chromosomes, has been implicated to be among the most common causes of implantation failure or miscarriages.

The Preimplantation Genetic Aneuploidy Testing (PGTA) is a genetic test performed on embryos to determine if the embryo is carrying a normal number of chromosomes. The chromosomal abnormal embryos are screened so as to select and transfer genetically healthy embryos. This increases the chances of attaining a healthy pregnancy and reduces the risk of miscarriages.

PGT-A (PGS) process involves removing a few cells from the developing embryo and testing them to determine if the embryo has the correct number of chromosomes. By selecting and transferring embryos with the correct number of chromosomes, PGT-A can improve the chances of a successful pregnancy.
