Polycythemia vera (PCV) (a.k.a. polycythemia rubra vera (PRV)) occurs when excess red blood cells are produced as a result of an abnormality of the bone marrow. [3] Often, excess white blood cells and platelets are also produced. A hallmark of polycythemia vera is an elevated hematocrit, with Hct > 55% seen in 83% of cases. [20]
The first is a very high red blood cell count, which is usually identified by elevated levels of hemoglobin or hematocrit; A bone marrow biopsy that shows hypercellularity and abnormalities in megakaryocytes; and; The presence of a mutation in the Janus kinase 2 (JAK2) gene.
Blood viscosity is determined by plasma viscosity, hematocrit (volume fraction of red blood cell, which constitute 99.9% of the cellular elements) and mechanical properties of red blood cells. Red blood cells have unique mechanical behavior, which can be discussed under the terms erythrocyte deformability and erythrocyte aggregation. [2]
A low hematocrit level is a sign of a low red blood cell count. One way to increase the ability of oxygen transport in red blood cells is through blood transfusion, which is carried out typically when the red blood cell count is low. Prior to the blood transfusion, hematocrit levels are measured to help ensure the transfusion is necessary and safe.
[2] [26] Pulmonary artery pressure increases in an effort to oxygenate more blood. Full hematological adaptation to high altitude is achieved when the increase of red blood cells reaches a plateau and stops. The length of full hematological adaptation can be approximated by multiplying the altitude in kilometres by 11.4 days.
An anemia is a decrease in number of red blood cells (RBCs) or less than the normal quantity of hemoglobin in the blood. [2] [3] However, it can include decreased oxygen-binding ability of each hemoglobin molecule due to deformity or lack in numerical development as in some other types of hemoglobin deficiency.
First, have your health care provider run blood tests to see if you truly have a B12 deficiency. If you do, the only way to treat it is to consume more B12, either through food, supplements or ...
The misshapen but otherwise healthy red blood cells are mistaken by the spleen for old or damaged red blood cells and it thus constantly breaks them down, causing a cycle whereby the body destroys its own blood supply (auto-hemolysis). A complete blood count (CBC) may show increased reticulocytes, a sign of increased red blood cell production ...
