What doctors know is that stored cord blood will remain effective for more than ten years once cryopreserved. New data supports the controlled rate freezing methods that most accredited cord blood banks currently use. Controlled rate freezing allows the blood to be cooled and frozen gradually to protect the integrity of the blood sample. Once the sample reaches â 196 itâs known that as long as the blood sample stays at this temperature with no variance that the blood sample is likely to remain intact and highly effective for more than ten years.
