  2. Anemia - Wikipedia

    en.wikipedia.org/wiki/Anemia

    A strict but broad definition is an absolute decrease in red blood cell mass, [63] however, a broader definition is a lowered ability of the blood to carry oxygen. [64] An operational definition is a decrease in whole-blood hemoglobin concentration of more than 2 standard deviations below the mean of an age- and sex-matched reference range .

  3. Blood cell - Wikipedia

    en.wikipedia.org/wiki/Blood_cell

    Hemoglobin is an iron-containing protein that gives red blood cells their color and facilitates transportation of oxygen from the lungs to tissues and carbon dioxide from tissues to the lungs to be exhaled. [3] Red blood cells are the most abundant cell in the blood, accounting for about 40–45% of its volume. Red blood cells are circular ...

  4. Akaryocyte - Wikipedia

    en.wikipedia.org/wiki/Akaryocyte

    Red blood cells are classified as akaryocytes because they lack a cell nucleus after they have fully developed. The most common types of akaryocytes are bacteria , and archaea . Bacteria and archaea are unicellular organisms that lack organelles–specifically, a nucleus. [ 1 ]

  5. Microcytic anemia - Wikipedia

    en.wikipedia.org/wiki/Microcytic_anemia

    The normal mean corpuscular volume (abbreviated to MCV on full blood count results, and also known as mean cell volume) is approximately 80–100 fL. When the MCV is <80 fL, the red cells are described as microcytic and when >100 fL, macrocytic (the latter occurs in macrocytic anemia). The MCV is the average red blood cell size.

  6. Monocyte - Wikipedia

    en.wikipedia.org/wiki/Monocyte

    One can see red blood cells, several knobby white blood cells including lymphocytes, a monocyte, a neutrophil, and many small disc-shaped platelets. A monocyte count is part of a complete blood count and is expressed either as a percentage of monocytes among all white blood cells or as absolute numbers. Both may be useful, but these cells ...

  7. Cytopenia - Wikipedia

    en.wikipedia.org/wiki/Cytopenia

    Anemia – a reduction of the red blood cells in the body.; Leukopenia – a deficiency of white blood cells, or leukocytes [1]; Neutropenia – a type of leukopenia, with a specific deficiency in neutrophils [2]

  8. Hematocrit - Wikipedia

    en.wikipedia.org/wiki/Hematocrit

    The hematocrit (/ h ɪ ˈ m æ t ə k r ɪ t /) (Ht or HCT), also known by several other names, is the volume percentage (vol%) of red blood cells (RBCs) in blood, [1] [2] measured as part of a blood test. [3] The measurement depends on the number and size of red blood cells. [3] It is normally 40.7–50.3% for males and 36.1–44.3% for ...

  9. Hemoglobinemia - Wikipedia

    en.wikipedia.org/wiki/Hemoglobinemia

    A hemoglobin test measures the amount of hemoglobin in your blood. If a hemoglobin tests shows that a person's levels are below normal, it means they have a low red blood cell count, which is known as anemia. If the test shows higher levels than normal, it means they have hemoglobinemia. [citation needed] The normal range for hemoglobin is:
