Summary

Umbilical cord blood (UCB) collection efficiency can be improved by refining donor selection criteria. Obstetric factors like placenta weight and newborn sex significantly influence nucleated cell count in UCB units.

Area of Science:

  • Hematology
  • Transplantation Medicine
  • Obstetrics

Background:

  • The limited cell dose in umbilical cord blood (UCB) hinders its widespread use in hematopoietic progenitor transplantation.
  • Donor selection is a critical area for improving UCB collection efficiency.

Purpose of the Study:

  • To analyze reasons for discarding UCB donors and units.
  • To identify obstetric factors influencing total nucleated cell (TNC) content.
  • To establish obstetric criteria for UCB donor selection.

Main Methods:

  • Evaluation of 391 maternal-neonatal pairs over 3 months.
  • Analysis of discard reasons for UCB donors and collected units.
  • Determination of obstetric factors affecting TNC in 1300 UCB units.

Main Results:

  • 32.5% of potential donors were refused; 38.9% of collected UCB units were discarded due to low cell counts.
  • Multivariate analysis identified placenta weight, newborn sex, and collection method as significant factors influencing nucleated cell count.

Conclusions:

  • Maternal medical histories require thorough review by medical staff prior to UCB collection.
  • Incorporating obstetric factors into standard UCB donor criteria can enhance bank efficiency and cell yield.
