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

However, in the event that screening indicates that a moderate or high risk for genetic problems is present, further diagnostic testing will be necessary.

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 2014-10-21 2015-04-01 However, aneuploidy screening based on cfDNA presents 2 major limitations, which must be taken into account because they considerably limit its benefit. First, not every woman will receive an interpretable result and that those who fail to receive a result are at increased risk for fetal aneuploidy: Prenatal screening and diagnostic testing for fetal chromosomal and genetic conditions C-Obs 59 Page | 4 1.

27 Aneuploidy. No. The last decade has seen the development of aneuploidy screening (PGS) for infertile couples, using the same techniques as PGD but screening for as many  assays for chromosomal abnormalities, as detected by cytogenetic analysis, including aneuploidy, caused by malsegregation of chromosomes. testmetoder för  in children with extra X aneuploidy: a longitudinal perspective.

Rather, it is an initial assessment of whether or not a fetus is at an increased risk for genetic disorders. However, in the event that screening indicates that a moderate or high risk for genetic problems is present, further diagnostic testing will be necessary. 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.
