Definition / general
  • Due to donor blood with a hemoglobinopathy, most commonly hemoglobin C
  • Abnormal hemoglobin ranges from 1 - 14% of recipient hemoglobin; recipient often has received multiple transfusions (Arch Pathol Lab Med 2006;130:1830)
  • Important to identify to avoid unnecessary testing and treatment; must also notify the donor
  • Important to send untransfused sample to test for hemoglobinopathy or red cell enzymatic defects
  • Detection of hemoglobinopathies may rarely be suppressed by transfusions (Arch Pathol Lab Med 2005;129:e107)
