lph Posted May 21, 2015 Share Posted May 21, 2015 If there is a suspected transfusion reaction but when inspecting the post sample there is no hemolysis present is it necessaryto compare the pre-transfusion sample to the post sample? This is in reference to AABB 7.4.2.1. Link to comment Share on other sites More sharing options...
Sko681 Posted May 21, 2015 Share Posted May 21, 2015 At minimum we do a DAT in addition to visual inspection for hemolysis on the post transfusion sample but I would caution that unless the post transfusion specimen is collected right away- hemolysis can be missed (I have personally seen it happen). kirkaw, Yanxia and Malcolm Needs 3 Link to comment Share on other sites More sharing options...
Malcolm Needs ☆ Posted May 21, 2015 Share Posted May 21, 2015 I would totally agree with the post by Sko681 above. The other thing is that the free haemoglobin in the plasma may only be detectable by something like light adsorption. Link to comment Share on other sites More sharing options...
