Delaying cord clamping reduces the amount of blood that can be banked. It may not be possible to delay cord clamping by more than 60 seconds and. Is cord blood banking compatible with delayed cord clamping.
After delayed cord clamping the amount of cord blood available for collection is reduced sometimes from as much as 55ml with immediate cord clamping to just 20ml.

The impact of delayed cord clamping DCC on public CB banking can be substantial.
Study design and methods. Cord blood units CBUs collected from 1210 mothers at one hospital were evaluated for total nucleated cells TNCs and weightvolume based on time to clamping. Bank staff recorded BTC time in seconds as reported by obstetricians.
Collections were performed ex utero. Delayed clamping of the umbilical cord after birth may benefit some infants by preventing iron deficiency. Implications of delayed cord clamping for public cord blood banking remains unclear.
