hello, i have a question for anyone who may be able to help. A recent request at my facility to transfuse a patient using a blood bank sample drawn and tested from another facility was posed to my supervisor. To my knowledge any patient drawn for a type and screen and an order for blood transfusion must be completed by the testing facility only, unless a reference lab is needed. This poses a serious issue of using the correct specimen for a crossmatch and identifiying the patient using a facility-specific medical record number. I have looked through the seventh edition of the AABB reference manual and have not found anything specific to my question. Has anyone else experienced this methodology and can a policy/procedure be created that would not contraindicate the AABB standards of practice?
