Hemoglobinopathies: three illustrative case studies
1Department of Laboratory Medicine, St. Joseph's Hospital, Hamilton, Ontario.
Three cases studies from the Regional Hemoglobinopathy Laboratory at St. Joseph's Hospital in Hamilton are presented. These cases demonstrate the diagnostic value of a comprehensive hemoglobinopathy screen, family studies, and appropriate clinical information in solving complex hemoglobinopathy problems. The first case is a 79-year-old woman found to have small amounts of an unknown hemoglobin migrating electrophoretically in the position of hemoglobin S. The second case describes a boy of Greek extraction with a thalassemic blood picture but otherwise normal hemoglobinopathy screen. The third case involves a 70-year-old man with a previously normal hemoglobinopathy screen who subsequently showed evidence of alpha thalassemia.
