When labeling blood components with recipient's information, what is required to be on the tag/label? We have one tag which we say must remain attached to the unit and another tag which is removed at the time of the bedside clerical check. The tag which is removed has the patient name, MRN, DOB, blood type of patient, blood type of unit, unit number, date and time of issue, also has listed if unit is Hemoglobin S negative or CMV negative, and results of crossmatch. On the tag which remains attached to the unit, the patient's name and mrn are listed as well as blood type of patient and unit. I am trying to find (unsuccessfully) what is required to be on the tag which remains on the unit. I looked in the technical manual and the CFR but am having trouble understanding what should be on the tag that remains. Any input or suggestions where to find this information would be much appreciated. Thanks!
