koorionbiopsia
Koorionbiopsia, also known as chorionic villus sampling (CVS), is a prenatal diagnostic technique used to detect chromosomal abnormalities and certain genetic disorders in a developing fetus. This procedure involves obtaining a small sample of tissue from the placenta, which is called the chorion. The chorion contains villi, which are finger-like projections that share the same genetic material as the fetus.
The procedure is typically performed between the 10th and 13th week of pregnancy. There are two main
The collected chorionic villus tissue is then sent to a laboratory for analysis. Geneticists examine the chromosomes
While CVS can provide valuable information about the fetus's genetic health, it does carry a small risk
