What is the typical volume of blood collected and how many stem cells could it contain?
A typical sample of cord blood will contain a volume in the region of 20ml to 60ml although this can differ dramatically due to the size of the placenta and circumstances at birth.
Though a larger cord blood volume generally points towards a higher stem cell yield this is not always the case. Some samples that are lower in volume can still provide a large amount of stem cells.
We can process any sample, though we do set a stringent success criteria based on the number of stem cell within it. The sample must contain a minimum of 200,000 CD34+ stem cells in order for us to deem it successful and suitable for long term storage. If your cord blood sample does not meet this requirement, you will have the option to decline storage and we will not charge you anything further.
