  2. Erythrocyte sedimentation rate - Wikipedia

    en.wikipedia.org/wiki/Erythrocyte_sedimentation_rate

    The ESR is decreased in polycythemia, hyperviscosity, sickle cell anemia, leukemia, chronic fatigue syndrome, [4] low plasma protein (due to liver or kidney disease) and congestive heart failure. Although increases in immunoglobulins usually increase the ESR, very high levels can reduce it again due to hyperviscosity of the plasma. [5]

  3. Hemoglobin A - Wikipedia

    en.wikipedia.org/wiki/Hemoglobin_A

    Individuals who have HbAS have about 40%HbS, 56% HBA, and are usually asymptomatic unless there is a severe lack of oxygen to the body (hypoxia) which can lead to symptoms of sickle cell disease. [12] However, HbAS does not cause vaso-occlusive crisis, which is known to be associated with sickle cell disease. [17]

  4. Acute chest syndrome - Wikipedia

    en.wikipedia.org/wiki/Acute_chest_syndrome

    The acute chest syndrome is a vaso-occlusive crisis of the pulmonary vasculature commonly seen in people with sickle cell anemia. This condition commonly manifests with a new opacification of the lung(s) on a chest x-ray .

  5. Hemoglobin electrophoresis - Wikipedia

    en.wikipedia.org/wiki/Hemoglobin_electrophoresis

    The test uses the principles of gel electrophoresis to separate out the various types of hemoglobin and is a type of native gel electrophoresis.After the sample has been treated to release the hemoglobin from the red cells, it is introduced into a porous gel (usually made of agarose or cellulose acetate) and subjected to an electrical field, most commonly in an alkaline medium.

  6. Priapism - Wikipedia

    en.wikipedia.org/wiki/Priapism

    Sickle cell disease is the most common cause of ischemic priapism. [3] ... Some sources give a duration of four hours as a definition of priapism, but others give six.

    Spleens are also removed for therapeutic purposes in conditions like hereditary spherocytosis, trauma to the spleen, and autosplenectomy caused by sickle cell anemia. Other causes are radiation therapy involving the spleen, such as that used to treat Hodgkin lymphoma .

    This would be similar to the hemoglobin allele which is responsible for sickle-cell disease, but solely in people with two copies; those with just one copy of the allele have a sickle cell trait and gain partial immunity to malaria as a result. This effect is called heterozygote advantage. [27]

  9. Spherocytosis - Wikipedia

    en.wikipedia.org/wiki/Spherocytosis

    A complete blood count (CBC) may show increased reticulocytes, a sign of increased red blood cell production, and decreased hemoglobin and hematocrit. The term "non-hereditary spherocytosis" is occasionally used, albeit rarely. [2] Lists of causes: [3] Warm autoimmune hemolytic anemia; Cold autoimmune hemolytic anemia/paroxysmal cold hemoglobinuria
