Cord Blood Collection

The Dangers of Heparin

Heparin is a highly controversial product that has been subject to much scrutiny over the past few years. Recent FDA recalls have heightened public awareness of the potential dangers of using this drug and its negative affects on umbilical cord blood.

When Heparin is used as an anticoagulant for blood collection it is broken down over periods of time beyond 12 hours.1 Heparin breakdown can lead to the irreversible formation of blood clots, which would render your baby's cord blood unfit for processing.

In a recent study comparing the effects of dry heparin to that of CPD, it was determined that cord blood units collected with liquid CPD contained significantly more viable stem cells than units collected with dry heparin.2

In 2009, the U.S. Department of Health and Human Services recommended only using citrate-based anticoagulants, such as Citrate Phosphate Dextrose (CPD), for the collection of cord blood. CPD acts as a cell preservative, as well as an anticoagulant, without the introduction of additional, unnecessary chemicals to your baby's cord blood.

MiracleCord is Heparin-free. CPD is used exclusively in our cord blood collection materials.
