Both whole cord blood and volume-reduced storage begin by collecting the available blood from the umbilical cord. The main difference between storing whole cord blood and volume-reduced storage is the methods used once the blood is received at the laboratory. Volume-reduction methods manipulate the sample to retain a proportion of one type of stem cell. In contrast, Cells4Life Platinum whole blood storage involves minimal manipulation with no separation of the blood. This optimises the number and types of stem cells stored.
