Hemoglobin C acquired via a blood transfusion. Detection by automated blood counter.

Hemoglobin C was acquired by a 52-year-old man via a blood transfusion. The presence of nonlysis of erythrocytes on the Technicon H6000 (Tarrytown, NY) scattergram after blood transfusions and the absence of this process in the admission peripheral blood count confirmed that this abnormal hemoglobin was acquired and not endogenous to the patient. Homozygous hemoglobin C disease was confirmed in one of the donors of blood received by the patient.
