KTUCK 1 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? Share this post Link to post Share on other sites
LIMPER55 19 Posted February 27, 2017 Yes because lis makes us but we crossmatch type O Share this post Link to post Share on other sites
Malcolm Needs ★ 4,713 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. Share this post Link to post Share on other sites

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. 3 pstruik, Ensis01 and galvania reacted to this Share this post Link to post Share on other sites
KTUCK 1 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 Share this post Link to post Share on other sites
Malcolm Needs ★ 4,713 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. 1 galvania reacted to this Share this post Link to post Share on other sites
kate murphy ★ 176 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. 2 CMCDCHI and Malcolm Needs reacted to this Share this post Link to post Share on other sites
mcgouc 63 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. Share this post Link to post Share on other sites
pinktoptube 45 Posted March 2, 2017 We give group O, so no AHG crossmatch. 2 TreeMoss and MaryPDX reacted to this Share this post Link to post Share on other sites
