What does AMR stand for?

have your lab director talk to the pathologist, His is not a tech call. THis is why your lab director gets paid the big bucks.

Clarifying question - Is it Friday afternoon or Monday morning?

I have seen this so many times and have always come to the conclusion that it was a mislabeled sample. Let us know what you find.

I see that you are not in the US. In US, ABO typing is considered non waived, high complexity testing. All those that do the test will need documented training, followed by competency assessment as well as documentation of education, i.e., diploma or transcripts. Do you have similar requirements in Brazil?

Agree with AMcCord. Can't and don't want to imagine nursing personnel performing this test.

I read a journal article a while back that looked at the detrimental effects to blood if left out at RT for different amounts of time and then but back in the fridge. They did this multiple times to each unit of blood. The result of their study was that the 30 minute rule, if there ever was one, could be changed to the 1 hour rule. I thought that was really interesting. Anyway, we take the temp of every red cell returned. If OK we put it back into inventory. The LIS will prompt for integrity/appearance acceptability and return temp.

what the heck does that mean?

I agree with David and would not bother with the expense of AABB accreditation.

I was being facetious. I haven't seen a bleeding time in decades.

What's a bleeding time?

Not all major ABO incompatibility transfusions result in death. I recently read somewhere that a few percentage (can't remember the exact number) up to 30% are fatal. In my career I have seen one not fatal and one fatal,.

I only do one comparison semiannually.

yes, yes, yes, yes!
