Abstract
An immune complex mechanism for ceftriaxone sodium- induced severe autoimmune hemolytic anemia has previously been demonstrated using routine blood bank techniques. We describe herein a patient with severe hemolysis that subsided once the drug was discontinued. Serologic techniques demonstrated immune complex-mediated ceftriaxone-dependent red cell antibodies. These findings were further supported by the results of flow cytometry, in which a change in basal red cell autofluorescence was seen in the presence of the antibody and the drug. Our case illustrates the adjunctive value of flow cytometry in the diagnosis of ceftriaxone-dependent red cell antibody.
