Anti-CD38 and Anti-CD47 Interference in the Blood Bank and Ways to Resolve Them


Biological therapies can be highly effective in treating malignancies but can cause interference with blood bank testing. Two monoclonal therapies directed at cluster designation antigens that cause red blood cell agglutination are highlighted: CD38 and CD47. This lecture will review the serologic reactivity and methods to abrogate blood bank interference.
