Hemoglobinopathy SD presenting as Hemoglobinopathy SS
This case report shows the interaction of hemoglobin (Hb) S with Hb D. in a child previously diagnosed with sickle cell anemia based on the Hb electrophoretic migration pattern in alkaline pH. The sickling phenomenon was confirmed with 2% sodium metabisulfite. The father and mother of the child had...
