KTUCK Posted February 27, 2017 Share Posted February 27, 2017 When performing compatibility testing with a patient who has Anti-A1, do you do a full cross match (through AHG phase) with the donor units? Link to comment Share on other sites More sharing options...
LIMPER55 Posted February 27, 2017 Share Posted February 27, 2017 Yes because lis makes us but we crossmatch type O Link to comment Share on other sites More sharing options...
Malcolm Needs ☆ Posted February 27, 2017 Share Posted February 27, 2017 I would certainly perform tests at 37oC, just to see if the anti-A1 is one of those exceedingly rare examples that may be clinically significant. If these tests are negative, I would not bother to go to the AHG phase. Link to comment Share on other sites More sharing options...

If it is your computer programme, I would urge that you change your computer programme so that it only makes you when the anti-A1 genuinely reacts at 37oC (pre-warmed, etc). A computer in the laboratory is there to aid the staff; not to make things more difficult. Ensis01, galvania and pstruik 3 Link to comment Share on other sites More sharing options...
KTUCK Posted February 27, 2017 Author Share Posted February 27, 2017 Our Lis does not flag. We rarely seem them. But I'm not even sure the LIS will flag if the donor selected is not O pos. I was curious so I could set up our LIS correctly. We have Soft, I'm not too fond of the Softbank portion of it. Thanks for you input Link to comment Share on other sites More sharing options...
Malcolm Needs ☆ Posted February 27, 2017 Share Posted February 27, 2017 Well, unless the anti-A1 really is one of the exceedingly rare clinically-significant ones, reacting at STRICTLY 37oC, the donor does not have to be group O - indeed, unless the anti-A1 does come into this incredibly rare type, you can very safely give blood from an A1 donor. galvania 1 Link to comment Share on other sites More sharing options...
kate murphy Posted February 28, 2017 Share Posted February 28, 2017 That makes sense, Malcolm, and I agree - but then there's that pesky IS incompatible crossmatch... Generally speaking, my techs don't like an IS incompatibility! So we give O. Or B, if the patient is AB. CMCDCHI and Malcolm Needs 2 Link to comment Share on other sites More sharing options...
mcgouc Posted March 2, 2017 Share Posted March 2, 2017 For years, we had a policy for determining the 37C reactivity, but we had a lot of generalists rotating through Blood Bank & there was no time to document their competency on a test they might do once in a great while. So, we went with B for AB and O for A. We were a small hospital & I determined it was only about 10 extra O units a year. Link to comment Share on other sites More sharing options...
pinktoptube Posted March 2, 2017 Share Posted March 2, 2017 We give group O, so no AHG crossmatch. TreeMoss and MaryPDX 2 Link to comment Share on other sites More sharing options...
