Characteristic

Preimplantation Genetic Testing for Aneuploidy (PGT-A, formerly known as PGS) is a test along with IVF to detect chromosomal abnormalities such as chromosome deletions/duplications in embryos before transfer. Through screening to select chromosomally normal embryos, the chance of miscarriage or fetal chromosomal abnormalities after implantation can be reduced. The success rate of embryo implantation in our partner institutions has increased significantly by 12-15% after using PGT-A screening, showing that our PGT-A test can indeed substantially improve the success rate of IVF. In addition, given the potential to reflect the comprehensive chromosomal profile of the whole embryo from cell-free DNA in spent culture medium, the non-invasive PGT-A (niPGT-A) shows promising advantages than PGT-A for clinical practices.
