“Cordocentesis, also referred to as Percutaneous Umbilical Cord Blood Sampling (PUBS) test, is a prenatal diagnostic test that can be used to determine whether there are any abnormalities present in a fetus. It consists of taking a sample of the fetus’s blood from the umbilical cord for further testing.

The test is typically performed after the 18^th week of pregnancy and can test for certain genetic conditions, blood disorders, and various infections. If need be, the procedure can also be used to give medication to the fetus through the umbilical cord, as well as blood transfusions.

Cordocentesis isn’t being used as much as it has in the past because there are other prenatal diagnostic tests that can be used instead that are less risky to the fetus, like amniocentesis or chorionic villus sampling (CVS). If other tests aren’t yielding enough information, though, cordocentesis is still performed.” Read More
