[Do you require a second specimen from a different draw when you have no history for a pre-transfusion candidate?]

How has anyone that has instituted patient blood management principles (including limiting phlebotomy losses) made it work with the drawing of 2 samples for blood type checking? Do you draw really small repeat samples? Just do a forward type or...?

For computer crossmatches AABB Standard 5.13.1 applies, which requires front and back typing.

The current CAP regs include a caveat when performing Computer Crossmatches "repeat testing of the same sample may be inadequate unless.......mechanical barrier..or digital bedside patient id.....".

[Metrics for Blood and Blood Component Wastage]

I have asked our local blood supplier for support in sharing this info among our collegues. They are working on it, having obtained and compiled some hospital data, but haven't shared it with their hospital customers yet.

They do provide color graphs showing our comparative type O RBC usage, so it's not a stretch to ask for this info to our benefit.
