In reviewing our emergency release policy we are required to obtain a post-transfusion sample after giving non-group specific blood and group specific blood may not be issued until an antiglobulin crossmatch can be shown to be compatible due to passive transfer of anti-A, anti-B, or anti-A,B from the O blood or the A plasma in our MTP protocol. Is anyone else doing this? Is there a standard I am not finding?

In the UK, the Guidelines say to swap to the patient's own blood group as soon as it is definitely ascertained, with no testing, whatever they have been given; it works.

Have never had to do that (from 24 bed to 700+ hospitals)

Seems unusual. I've only seen crossmatching the segments of the units that the pt ended up taking from the emergency release. Once our T/S is done we start sending type specific.
