Preimplantation genetic testing for aneuploidy (chromosomal abnormality) (PGT-A), also known as preimplantation genetic screening (PGS), is a very early method of screening the chromosomal make-up of embryos with the aim of increasing the pregnancy rate and reducing the risk of miscarriage for specific groups of patients.

aneuploidy screening of embryos derived from patients undergoing IVF, also termed preimplantation genetic screening (PGS), enables the assessment of the numeral and structural chromosomal constitution of embryos before transfer. It has been applied to treat patients with increased risk for aneuploid embryos, and then intro-

While aneuploidy screening is strongly recommended by medical professionals, it is an optional screening in your prenatal care. Whether or not to receive genetic screening is a personal decision and it is in a woman’s best interest to consider how such screening will affect her pregnancy depending on the results.

The accuracy of new molecular diagnostics, fluoresence in situ hybridization or quantitative fluorescence-PCR (collectively known as rapid aneuploidy screening), in prenatal diagnosis has already been demonstrated in a number of large studies. The challenge now is how to apply them clinically in the most cost-effective manner.
