  2. Reticulocyte production index - Wikipedia

    en.wikipedia.org/wiki/Reticulocyte_production_index

    The reticulocyte production index (RPI), also called a corrected reticulocyte count (CRC), is a calculated value used in the diagnosis of anemia. This calculation is necessary because the raw reticulocyte count is misleading in anemic patients. The problem arises because the reticulocyte count is not really a count but rather a percentage: it ...

  3. Reticulocytosis - Wikipedia

    en.wikipedia.org/wiki/Reticulocytosis

    In response to significant blood loss, either acute (e.g., trauma or surgery) or chronic (e.g., gastrointestinal bleeding), the bone marrow increases production to replace lost red blood cells. This results in an increased reticulocyte count, as new immature cells are released and make up a larger proportion of the blood volume. [2]

  4. Reticulocyte - Wikipedia

    en.wikipedia.org/wiki/Reticulocyte

    A reticulocyte percentage that is higher than "normal" can be a sign of anemia, but this depends on the health of a person's bone marrow. Calculating the reticulocyte production index is an important step in understanding whether or not the reticulocyte count is appropriate to the situation. This is often a more important question than whether ...

  5. Nucleated red blood cell - Wikipedia

    en.wikipedia.org/wiki/Nucleated_red_blood_cell

    Nucleated red blood cell. A human peripheral blood smear; NRBCs are visible as larger cells with dark centers. A nucleated red blood cell (NRBC), also known by several other names, is a red blood cell that contains a cell nucleus. Almost all vertebrate organisms have hemoglobin -containing cells in their blood, and with the exception of mammals ...

  6. Anemia - Wikipedia

    en.wikipedia.org/wiki/Anemia

    The reticulocyte production index is a calculation of the ratio between the level of anemia and the extent to which the reticulocyte count has risen in response. If the degree of anemia is significant, even a "normal" reticulocyte count actually may reflect an inadequate response.

  7. Reticulocytopenia - Wikipedia

    en.wikipedia.org/wiki/Reticulocytopenia

    Reticulocytopenia is the medical term for an abnormal decrease in circulating red blood cell precursors (reticulocytes) that can lead to anemia due to resulting low red blood cell (erythrocyte) production. [1] Reticulocytopenia may be an isolated finding or it may not be associated with abnormalities in other hematopoietic cell lineages such as ...

  8. Sickle cell disease - Wikipedia

    en.wikipedia.org/wiki/Sickle_cell_disease

    Sickle cell disease (SCD), also simply called sickle cell, is a group of hemoglobin-related blood disorders typically inherited. [2] The most common type is known as sickle cell anemia. [2] It results in an abnormality in the oxygen-carrying protein haemoglobin found in red blood cells. [2] This leads to the red blood cells adopting an abnormal ...

  9. Erythropoiesis - Wikipedia

    en.wikipedia.org/wiki/Erythropoiesis

    Erythropoiesis is the development of mature red blood cells from erythropoietic stem cells. The first cell that is morphologically recognizable in the red cell pathway is the proerythroblast. In the basophilic erythroblast, the nucleus becomes somewhat smaller, exhibiting a coarser appearance, and the cytoplasm becomes more basophilic owing to ...
