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

2020-05-15 Aneuploidy is the presence of one or more extra chromosomes or the absence of one or more chromosomes. The risk of fetal aneuploidy rises with increasing maternal age. … 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. aneuploidy screening The testing of embryos for evidence of sex-linked diseases and structural chromosomal defects before their implantation in the uterus during assisted reproduction.

Several molecular techniques have been utilized during IVF cycles to determine ploidy including ﬂuorescence in situ hy-bridization (FISH), comparative genomic hybridization (CGH), array CGH (aCGH), digital polymerase chain reaction (dPCR), single-nucleotide polymorphism (SNP) 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.

genetic testing for aneuploidy (PGT-A). Several molecular techniques have been utilized during IVF cycles to determine ploidy including ﬂuorescence in situ hy-bridization (FISH), comparative genomic hybridization (CGH), array CGH (aCGH), digital polymerase chain reaction (dPCR), single-nucleotide polymorphism (SNP) Prenatal screening for aneuploidy has changed significantly over the last 30 years, from being age-based to maternal serum and ultrasound based techniques. Multiple pregnancies present particular challenges with regards to screening as serum-based screening techniques are influenced by all feti while ultrasound-based techniques can be fetus specific.
