Cord blood needs to be preserved by specialized medical institutions. There are two forms of cord blood storage: autologous storage and public storage. 1. Autologous bank: that is, personal preservation, before the baby is born, tell the obstetrician to contact the umbilical cord blood preservation organization, and then the doctor or midwife who delivers the baby promptly collects the umbilical cord blood at the first time after the baby is born. The doctor at the preservation organization will bring it back in time for preservation. This method of preservation entails a significant cost. In the event of disease, you are guaranteed to have original blood that is perfectly suited for your match. 2. Public bank: that is, donate to the state, donate the cord blood directly to the state, have the state organization to save it, and will issue the donation certificate after donation. Once your family members need cord blood to treat diseases in the future, you will have the priority to use it, and there is no cost. It is up to the individual to choose the method of preservation according to his/her financial situation.
