When we run into scenarios like this we will routinely test against the more common low incidence antigens (e.g. Jsa, Kpa, Cw). I think it makes all of the techs feel better.

I agree with every word you say Phil, EXCEPT that, as the baby is fine, trying to identify an antibody directed against a low-prevalence antigen is like hitting your head against a brick wall, over and over and over again! One has to remember that it is not just the specificities within the 701 series (assuming that it is not a novel specificity all together), but most of the "larger" Blood Group Systems also contain low-prevalence antigens (just look at the Diego Blood Group System, as an example); you could spend many "happy" hours testing the plasma, and still get nowhere. So, the serologist in me says "YES", the pragmatist in me shouts "NO"!!!!!!! The thing is, the next pregnancy, if there is one, should, without doubt, be closely monitored (probably by MCA Doppler, or something similar), but, if either an IUT or an exchange transfusion (or a top-up transfusion, come to that) is required, finding compatible blood would be easy, even without knowing the actual antibody specificity.

It's going to detect ABO incompatibility if the right patient was drawn. Our practices are meant to prevent transfusion of ABO incompatible blood due to wrong blood in tube (WBIT) incidences. Edit: If you are concerned only with patients who qualify for electronic crossmatch then that is slightly different issue, to be sure. I do not think everyone in this thread is using this information for EXM purposes only, though.

Sigh - I guess I'll go bck to cleaning off my workbench in the cellar....

You get far less for murder these days Cliff!!!!!!!!!

The reference lab updated the report and now calls it a warm auto with little c specificity. They also say that c negative blood is not necessary and transfused cells should survive as long as his own. his hgb is down to 10.7. He is still in house. Still no hematologist on the case. Barbara

Is anyone using the Mapping Dictionary in Meditech's MIS Applications to automatically order extended crossmatches for patients with a history of clinically significant antibodies? As I understand the "Best Practices" information, this will automatically order an extended crossmatch once an intervention in MIS is performed (the Replace Crossmatch Test routine is used to associate the Crossmatch Test Map with a patient history.)

Here's mine too - if it will help anyone. Very difficult to get everyone through and despite telling them it is THEIR responsibility - you wind up doing the lion's share of it in order to get it done. Blood Bank Competency 2014.xls Blood Bank Skills 2014.xls
