Three cases of multiple myeloma showing ABO discrepancy / 대한수혈학회지

ABSTRACT

We report 3 cases of multiple myeloma showing ABO discrepancy with missed reaction in serum typing. They showed markedly decreased immunogolobulin level except for monoclonally increased abnormal immunoglobulin. Their blood group was confirmed by saliva test and addition of anti-globulin reagent. As serum immunoglobulin level is raised, the reactivity in serum typing showed improving tendency and ABO discrepancy appeared when immunoglobulin was markedly decreased.
