How much time is cord blood allowed to spend traveling to the laboratory?

Public cord blood banks throughout the world have adopted a time window of 48 hours as the maximum delay from birth to the initiation of lab processing.  It would be a "best practice" if family banks also followed the 48 hour window.

Some data points:

  • FACT accreditation standards require the 48 hour window for public donations but allow 72 hours for family banks.
  • AABB accreditation standards do not specify a time window.
  • The US FDA recommends the 48 hour window.
  • The US state of NY Dept. of Health requires a 48 hour window.
