This is a must read for Expectant parents. One must know all about umbilical cord blood and their advantages and disadvantages, before heading to cord blood bank. One should be aware of the truth that the odds that a child will ever use his or her own stored cord blood are small. Also currently, it is unknown how long umbilical cord blood will maintain its usefulness while frozen, some says 15, some says 20, some says lifelong. The potential benefits and limitations of allogeneic (from different individual) and autologous (same individual) cord blood banking and transplantation should be known. Even then, storing umbilical cord blood is definitely a good option, but whether one should opt for public or private bank, the decision must be taken after understanding the pros and cons of UCB (Umbilical Cord Blood) and understanding the science around it.
