What are some of the precautions related to using records in the TS?
Although records play a key role in the TS, there are precautions associated with their use. Some records may be used without confirmation but most require current testing:
Historical ABO blood groups are never used to issue RBC since misidentification and clerical errors can result in life-threatening hemolytic transfusion reactions.
ABO and Rh records on cards carried by patients are never used for transfusion purposes since they are totally unreliable.
