Funiculocentesis, also called cordocentesis, is an invasive prenatal diagnostic test to detect congenital and blood abnormalities in the fetus. This test involves puncturing the umbilical cord of the fetus to obtain its blood and analyzing it.
Funiculocentesis is usually performed between the 18th and 23rd week of pregnancy, although it can also be performed at a later time.
As with any diagnostic technique, this invasive prenatal test can pose a risk to both mother and fetus. The main danger of funiculocentesis is the possibility of miscarriage. For this reason, it is an underused diagnostic method at present.
