Sickle cell disease (SCD), also simply called sickle cell, is a group of hemoglobin-related blood disorders that are typically inherited. [2] The most common type is known as sickle cell anemia. [2] Sickle cell anemia results in an abnormality in the oxygen-carrying protein haemoglobin found in red blood cells. [2]
[18] [19] In 1950, Itano and James V. Neel discovered from two African-American families a different blood condition very similar to sickle cell disease. [20] [21] Five of the ten individuals indicated sickled RBCs. But the condition was harmless as the individuals had no anaemia. Thus, it was not clear whether it was involved in sickle cell ...
Hemoglobin electrophoresis is a blood test that can detect different types of hemoglobin. The test can detect hemoglobin S, the form associated with sickle cell disease, as well as other abnormal types of hemoglobin, such as hemoglobin C. It can also be used to investigate thalassemias, which are disorders caused by defective hemoglobin production.

CNN staffer Sharon Browne-Peter was diagnosed with sickle cell disease before she was born and needs regular blood transfusions to stay healthy. Ethnically-matched blood offers the best treatment ...
Those who are heterozygous for the sickle cell allele produce both normal and abnormal hemoglobin (the two alleles are codominant with respect to the actual concentration of hemoglobin in the circulating cells). Sickle cell disease is a blood disorder wherein there is a single amino acid substitution in the hemoglobin protein of the red blood ...
Each year about 300,000 infants are born with major sickle-cell disorders—including more than 200,000 cases in Africa A 10-minute test could solve Africa’s sickle cell disease screening ...
Poikilocytosis is variation in the shapes of red blood cells. Poikilocytes may be oval, teardrop-shaped, sickle-shaped or irregularly contracted. Normal red blood cells are round, flattened disks that are thinner in the middle than at the edges. A poikilocyte is an abnormally-shaped red blood cell. [1]
