The cells in the umbilical cord blood die from the time of the umbilical cord blood harvesting till the end of the processing. In the first 48 hours all the stem cells survive, in 72 hours 5% of the cells die off, in 96 hours 10% of the cells die off, after 96 hours the dying off of the cells rapidly accelerates, and on top of that, the character of the stem cells seems to be changed.

          We guarantee umbilical cord blood processing within 72 hours from the harvesting (otherwise we arrange the transplant free of charge). The average period from the harvesting till the end of the processing is 39 hours in our company. Some companies declare the delivery time of the umbilical cord blood to the laboratory, though this time is irrelevant as the cells further die out until the end of the processing. For comparison it we will declare this time too: the umbilical cord blood is latest in 64 hours in the laboratory after the harvesting, the average time is 31 hours.

Simultaneously we guarantee transport in a temperature range that not endanger the cells; the transport temperature is monitored all the time by a microchip, which is the part of the transport bag, that allows the trace-back control of the whole transport. The way of packing and the transport was developed to preserve the optimum temperature during transport and it is systematically verified by analysis of data from monitoring microchips located in the transport bag together with the umbilical cord blood.

Find out if the time data presented by the company means the time from the birth to the end of the processing. As long as the umbilical cord blood is processed within 48 hours we do not consider this fact as important. However, we consider as unacceptable the processing after 96 hours from the harvesting.

Verify, if the company monitors the umbilical cord blood temperature and how the umbilical cord blood is secured against extreme temperature deviations.
