Second trimester serum screening is offered between 15 and 20 weeks gestation. It is preferable to do the test as soon after 15 weeks as possible.

Given the high degree of concordance between NGS and array-CGH, NGS-based aneuploidy screening appears to be a robust methodology ready to find a place in routine clinical application. Second trimester serum screening is offered between 15 and 20 weeks gestation. It is preferable to do the test as soon after 15 weeks as possible. The risk of aneuploidy and ONTD is reported in a second trimester serum screening (STSS) report. (Figure 1) Figure 1: Aneuploidy Screening in Saskatchewan - The Biochemistry Option 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- The first phase, involving a large preclinical validation study on single cells, demonstrated that the NGS-based 24-aneuploidy screening protocol was accurate and reliable (Fiorentino et al., 2014). The results provided 100% consistency for aneuploid embryo call with array-CGH, a well-established and highly validated method of aneuploidy screening.

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.

Innan provtagning NIPT is the most accurate prenatal aneuploidy screening test available. 1-5.
