At my hospital we reject 1-2 cord specimens a day on the basis of labelling errors. Our SOP is that all specimens including cord blood are labelled correctly. We consider the cord blood is a baby's specimen and as such it must be labelled with the baby's name, UR and/or Date of birth. When Mary Smith has her baby it is given the name: Smith, baby of Mary. (this is the babies name - even though it incorporates the mother;s name) If specimens arrive in the lab with both maternal and baby stickers the specimens will be rejected, We do not make any exceptions for cord bloods, as we would reject all specimens labelled with more than one person's details. Rejecting specimens is always unfortunate but it is hoped that by stictly following protocol the incidence of errors will decrase - it is happenning slowly.
