c. hemoglobin C trait d. hemoglobin C disease e. hemoglobin SC disease 12. A 57-year-old female presents with incidentally discovered leukocytosis (WBC > 90 × 103/μL). Her peripheral blood smear reveals many immature granulocytes including a relative expansion in the number of myelocytes, ...
Blood smear –many target cells; sickle cells occasionally seen. 3. Sickle cell preparations – positive. 4. Hemoglobin electrophoresis –SC pattern (Hb S ∼50%; Hb C ∼50%). Clinical Features 1. Similar to, but usually less severe than, sickle cell disease-SS. 2. Severe infarctions ...
Crystal formation (classically, hexagonal-shaped crystals on peripheral blood smear) may result, which can lead to increased blood viscosity and cellular rigidity and shortened erythrocyte survival. Unlike sickle cell disease (SCD), Hb C does not cause linear intracellular polymerization of red cells ...
~xamGation of the peripheral blood smear disclosed slight hypochromia and anisocytosis. The patient received a therapeutic trial of multivi- tamins with iron, but the anemia persisted. Over the next 5 years, the patient received several courses of oral elemental iron therapy, without improvement...
Hemoglobin C diseaseThe typical rod-shaped HbC crystals in the peripheral blood smear often provide the diagnostic clue to the HbC disease. This case highlights that a careful review of blood film morphology may be helpful to detect HbC disease, although this case's routine blood test is normal...

Type IV: enzyme deficiency limited toerythrocytesErythrocytesErythrocytes, or red blood cells (RBCs), are the most abundant cells in the blood. While erythrocytes in the fetus are initially produced in the yolk sac then the liver, the bone marrow eventually becomes the main site of production.Ery...
It was also between 11 and 15 weeks of age that the blood smear became normal. By 7 months of age the infant's electrophoretic pattern was identical with that of her mother. At this time the variant hemoglobin accounted for about 20% of the total in both mother and propositus (Table 1...
(Method: Microscopic examination of treated and stained peripheral blood smear) Less than 1% fetal cells present. Description The Kleihauer-Betke test is used to determine the degree of fetal-maternal hemorrhage (FMH) and to help calculate the dosage of Rh immune globulin (RhIG)—Rho(D) RhoGA...
Therefore, Heinz bodies are often detected only in a blood smear after splenectomy. Erythrocytes with Heinz bodies also have a high affinity to attach to the vascular endothelium. In some variants, oxidatively acting substances, drugs (Table 2), and infections trigger hemolytic crises. A classic ...
