Think someone was talking bull to you.(Original post by Helenia)
Oh ok, didn't know that - was the case when we had our med school teaching and at my hospital last year.
Don't get me wrong you do waste blood by over crossmatching - basically you end up reserving the blood for so long it goes beyond its best before date and expires.
But if blood is crossmatched for patient A on admission and he dies before it leaves the lab, and someone actually bothers to tell the lab then it will go back into the general pool.
Of course electronic issue crossmatches help reduce this waste because you can get an issue so quickly people now are less likely to over order.
[Incidentally I only properly understood all this once I did a haem job and spent time in the lab]
When can you expect yours?
