aneuploidy screening

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. Aneuploidy screening is one means of decreasing the risk of genetic diseases in implanted embryos.

9] This technique also enabled us to provide rapid results with conclusive outcomes within 24 hours of receipt of the sample, [5,9,11,12] which is about half the time of fast FISH aneuploidy screening, because it is possible to interpret the profiles of several samples in few minutes.

The question was posed whether routine ultrasound would prove beneficial in a developing country, such as South Africa, where high rates of perinatal morbidity and mortality prevail (Department of Health, 2002:9; Berkowitz, 1993:1-3) and where routine aneuploidy screening is not currently feasible.
