Amniocentesis is to detect abnormal karyotype such as trisomy 21 or Down syndrome. For this it is necessary to culture cells and also to measure the concentration of alpha-fetoprotein (a marker of neurological abnormality such as spina bifida). The mother will undergo a levy so that only last a few minutes. Read the rest of this entry »
Maternal blood, an interesting tool for exploring DNA Baby
Before placing in the world, a child is exposed to possible genetic diseases they inherit from his parents. These diseases could be diagnosed by the methods called amniocentesis or the chorionic villus sampling. It goes without saying that these methods are very effective but unfortunately dangerous for the baby: there was a 0.7% increase in the number of miscarriages as a result of the examinations.
Fortunately, medicine is evolving and it can open up new perspectives. Thus, a team of researchers from the University of Hong Kong came to isolate the DNA sequence of a fetus through the mother’s blood. The result is that they were able to identify 94% fetal genome. Read the rest of this entry »

- A risk of chromosomal abnormality that can cause genetic diseases related to sex of child
- A risk of trisomy 21
- A risk of hereditary diseases
- Risk of malformations of the central nervous system.
