Percutaneous umbilical cord blood sampling prepared with an anticoagulant, which helps to reduce the risk of clot formation. During the procedure, the first step is to locate a relatively stable segment of the umbilical cord.

However, if the placenta is in the posterior position, the fetus might block direct access to the umbilical cord. Once the umbilical cord is
