Additionally, these methods are able to differentiate homozygous SCD (HbSS, sickle cell anemia) from double heterozygous inheritance of the sickle gene and other abnormal hemoglobins (eg, HbSC, HbSD, Hb S/β-thalassemia, and HbSO-Arab). The peripheral smear shows sickle cells (Fig. 3). ...
Peripheral smear showed mild microangiopathic changes with 0-1 schisctocytes per hpf without evidence of sickle cells. Hematology was consulted and the patient was started on plasma exchange for a presumed diagnosis of TTP, however it was discontinued when his ADAMTS13 returned at a low-normal...

How do you make the diagnosis of sickle cell anemia? Hemoglobin electrophoresis shows the presence of hemoglobin S. The peripheral smear shows characteristic sickle cells, and, often, Howell-Jolly bodies Hematological indices in individuals with HbSS? Individuals with HbSS have low Hb and low RBC ...
In fact, each year hundreds of thousands of blood smear slides are prepared in sub-Saharan Africa to make diagnosis of blood cell infections and disorders15. Peripheral blood smears, exhibiting variations in e.g., the size, color, and shape of the red blood cells can provide diagnostic ...

Blood smear(also called peripheral smear and manual differential)—a trained laboratorian looks at a thin, stained layer of blood on a slide under a microscope. The number and type of red blood cells are evaluated to see if they are normal. Sickle-shaped RBCs may be seen on the blood smea...
A nurse is discussing a granulocyte. Which type of cell is the nurse describing? A. Platelets B. T cells C. Neutrophil D. Erythrocyte A patient presents with mild normochromic, normocytic anemia. On the peripheral smear, there are a few target cells, a ...

and ISCs are not seen on the peripheral blood smear. The usual partition of Hb A and Hb S in sickle cell trait is 60 : 40 owing to a greater posttranslational affinity of α chains for βAthan for βSchains.6When α-thalassemia is coinherited with sickle cell trait, the preferent...
