[Two different techniques for volume blood reduction obtained from umbilical cord].

Background: To preserve the umbilical cord blood (UCB), the volume containing the cells must be reduced before freezing, but the quality, quantity and functionality of the cells has to be preserved during this procedure. The aim is to compare the performance of two different techniques for volume reduction.

Methods: A semiautomatic system and an automatic system were compared as two different UCB volume reduction techniques.
