The study explores whether human genomic DNA exists in the plasma of cord blood (CB) units, which could assist in accurate genetic identification.
The researchers confirmed that extracellular DNA (EC-DNA) levels are significantly higher in CB plasma compared to adult plasma and noted that these levels increase over time with reduced cell viability.
These findings suggest that using EC-DNA from CB plasma could reliably verify the identity of plasma aliquots in CB banking, enhancing traceability and safety in transplantation.
