Screening for the risk of fetal aneuploidy can be effectively performed in either the first or second trimester. When obtained independently, the interpretation of those data is straightforward. However, the effectiveness of screening can be enhanced by combining studies performed in each trimester in a variety of ways. The use of circulating cell-free DNA (cfDNA) for detecting fetal aneuploidy has transformed the landscape of prenatal screening since its introduction in 201 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. Our safe, non-invasive first trimester screening tests are based on biochemical markers from maternal serum and provide expectant parents with a risk assessment for trisomy 21, 13, and 18.

PGS (Aneuploidy screening) 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. Screening based on the NT alone is insufficient for aneuploidy risk evaluation because of a lower detection rate of approximately 70%, although NT alone may be used to screen women with high-order multiple gestations (triplets or quadruplets), as there are currently no effective serum screening options for these pregnancies.
