Crangel 0 Posted December 1, 2016 If DAT is the same as last workup but the patient has made an antibody, is an elution being done???? Patient was transfused a week ago. Please give your thoughts. Thanks Share this post Link to post Share on other sites
Malcolm Needs ★ 4,459 Posted December 1, 2016 As long as a new specificity is detected in the plasma, I wouldn't UNLESS the patient requires a further transfusion. in which case I would do an elution and test it against red cels that do not express the antigens against which the plasma is known to contain antibodies (including the de novo specificity). 1 StevenB reacted to this Share this post Link to post Share on other sites
