Fetal blood sampling or cordocentesis is a straightforward procedure where fetal blood is typically accessed at the site of the umbilical vein, using a long, small‐gauge spinal needle. Access to fetal blood via the hepatic vein or heart (cardiocentesis) has also been described. Fetal blood sampling is performed for various indications such as cytogenetic diagnosis, congenital infection, and fetal anemia. It is rarely performed for the evaluation of fetal coagulopathies and platelet disorders, given the potential risk for fetal hemorrhage secondary to the pathologies suspected. Most of the time cordocentesis is performed as the precursor to fetal transfusion.
