After your baby’s cord blood has been collected, your obstetrician or midwife will clamp and cut a segment of the umbilical cord. This cord will be stored in a sterile container provided in your Umbilical Cord Collection Kit.
The umbilical cord collected is then sent to Cordlife's laboratory for processing and cryopreservation . Prior to umbilical cord processing, the identity of the umbilical cord collected is verified by our laboratory technologist to ensure that the unit belongs to the right client.
All subsequent steps are performed in a biohazard safety cabinet to further eliminate the risk of contamination.
Next, the umbilical cord is further processed, cleaned with wash buffer solution and segmented into small pieces.
The sterilized tissue sections are then transferred into multiple cryovials added with cryoprotectant solution to safeguard the viability of the stem cells in the tissue sections during cryopreservation.
Once the cryoprotectant solution has been added, the tissue sections are frozen gradually in the controlled-rate freezer, where the temperature is lowered by 1-2°C per minute to preserve the viability of the stem cells.
After the controlled-rate freezing process, the cryovials are transferred into a MVE anti-contamination vapour-phase liquid nitrogen storage system for long term cryopreservation at -190°C
