Transfusion reaction workups that are negative (no hemolysis, DAT neg, clerical checks OK, etc.) are left for the next business day for the pathologist to review. I am curious how many institutions wait for pathologist approval to continue transfusions. Currently transfusion reaction workups that are negative, the tech releases any additional units for transfusion, but our new blood bank pathologist is reconsidering this policy. A review of CAP and AABB regulations do say one way or the other unless I missed something.
