Yes! Allergic/anaphylactic blood transfusion reaction is within minutes to 2-3 hours.
(pg 114 of the 2019 FA has a list of them ordered by time)
(also allergy / anaphylactic presents with more skin findings (urticaria, pruritus)
The time through me off too. I though ABO mismatch since it occured around an hour. I thought TRALI would take a little longer.
Guys anaphylactic reaction to whole blood doesnt occur much except for selective IgA defi. so look out for prev history of mucosal infection. And it can have all feature of type 1 HS inclding bronchospasm.
I saw hypotension and though anaphylaxis........ -.-
