Naturally Occurring Anti-Jk ^a : Expanding the Evidence beyond Sensitization

These findings provide further evidence that anti-Jk^a can arise naturally, independent of sensitizing events. Detection was possible through solid-phase testing, highlighting its ability to identify weak or developing antibodies that may be missed by conventional tube methods. Awareness of such naturally occurring Kidd antibodies is essential to ensure appropriate antibody identification and selection of compatible blood for transfusion.
