Preimplantation Genetic Screeing (PGS)
The PGS test provides information of embryos in case of chromosomal anomalies.
The PGS is normally used to evaluate embryos, with the help of a cell biopsy and test. We look for normal amount of chromosomes (named euploidy). During the fertilization an embryo has 23 chromosomes from both parents (a total of 46). An abrnormal amount of chromosomes (named aneuploidy) causes birth defects and failed pregnancies. Common conditions due to chromosomes anomalies include:

Down's Syndrome
Turner's Syndrome
Klinefelter Syndrome
If individuals or couples suspect a chromosome anomaly causing the above illness, a PGS is recommended where a geneticist performs a thorough evaluation of the family history.
