Louisiana has state legislation around cord blood education that follows the Institute of Medicine guidelines and mandates/encourages physicians to educate expectant parents about ALL forms of cord blood banking. The Louisiana bill was enacted 12 June 2008 and became effective 15 Aug. 2008.
- What is the allowed time window for shipping cord blood to the lab?
- 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.
- What questions should parents ask a Family Bank about Laboratory Standards?
- Is the cord blood laboratory accredited by an agency that has specific standards for cord blood banks and conducts inspections? (ex: AABB, FACT, ISO)
- Some US states license cord blood banks (CA, MD, NJ, NY): Do they operate in those states? Note that the California Biologics License is based on AABB accreditation, but lags behind the latest AABB updates.
- Does the lab process cord blood around the clock, or only on selected shifts?
- What tests does the lab perform on maternal blood?
- What tests does the lab perform for infectious disease markers?
- What tests does the lab perform for contamination?
- Does the lab ever reject cord blood collections on the basis of the tests of maternal blood, infectious diseases, or contamination?
- Does the lab maintain a "quarantine tank" for the storage of blood that might be able to transmit an infection?
- What tests does the lab perform to measure the stem cell count of the processed cord blood and the stem cell viability?
- Does the lab/bank inform parents, prior to storage, if the collection is too small for a transplant, and give them the option not to save it?
- Does the lab/bank offer parents a refund if the cord blood collection has certain problems (contamination, low volume)? These refunds are typically only offered if the bank performed the collection as part of their service.
- What information will parents receive in the final report about their stored cord blood?
- What is delayed cord clamping?
Some people feel that the blood in the umbilical cord should be allowed to flow into the baby and that the cord should not be clamped while it is still pulsing. Medical studies have shown that, particularly in parts of the world with poor infant health care, delayed cord clamping can help protect the baby from anemia (low blood counts) during the first 6 months of life. However, a prolonged delay will allow the blood in the cord to clot, and the opportunity to collect the blood for stem cells will be lost. Therefore, if clamping is delayed, it should not be more than two minutes.
