Due to the geopgraphy of the site and location of laboratories in relation to key areas we have a number of O negtive units issued to "EMERGENCY ISSUE". The units have their own individual paperwork and labels for insertion in the patient's notes. The laboratory has a record sheet of the Key locations and units issued for "emergency". When blood has been used paperwork is returned with details of the patient recieving the unit(s) and replacem,ent made. Where a patient's unique identifiers are known units (group specific where time permits) are issued with labelling which conations facility to return an acknowledgement of use.
