Electronic Crossmatch

[Kathy3171]

We are currently validating EXM for our hospital for Meditech 6.0. My questions are, when you are typing the same sample for the second time can you do an abbreviated front type or a full type--my thoughts are a full type. My second question is how do you label units as to compatibility?

In answer to the first of your questions, what do you do for your ABO typing? Do you use anti-A, anti-B and anti-A,B or just anti-A and anti-B?

The reason I ask is that many anti-A,B reagents are, actually, a blend of monoclonal anti-A and monoclonal anti-B. If this is the case, then I can see no reason to repeat the anti-A,B (actually, to be honest, if that is the case, I can't really see the point of using the anti-A,B in the first place, but that is an argument for another post/thread/day!).

Depending upon the rules (and I'm not familiar with the rules outside the UK - actually, substitute "I am completely ignorant" for "I'm not familiar") you may or my not be able to abandon a second reverse group.

As to your second question, I'll leave that to be answered by someone who actually does it!

If you are following AABB Standards, a complete type is required. The computer crossmatch standard (5.15.2.2) references the ABO Group Standard (5.13.1) that specifies both forward and reverse types are performed.
