  2. Red blood cell indices - Wikipedia

    en.wikipedia.org/wiki/Red_blood_cell_indices

    Mean corpuscular volume (MCV) is the average volume of a red blood cell and is calculated by dividing the hematocrit (Hct) by the concentration of red blood cell count. [citation needed] = [] Normal range: 80–100 fL (femtoliter)

  3. Polycythemia - Wikipedia

    en.wikipedia.org/wiki/Polycythemia

    Polycythemia is defined as serum hematocrit (Hct) or hemoglobin (HgB) exceeding normal ranges expected for age and sex, typically Hct >49% in healthy adult men and >48% in women, or HgB >16.5 g/dL in men or >16.0 g/dL in women. [8] The definition is different for neonates and varies by age in children. [9] [10]

  4. Reference ranges for blood tests - Wikipedia

    en.wikipedia.org/wiki/Reference_ranges_for_blood...

    A reference range is usually defined as the set of values 95 percent of the normal population falls within (that is, 95% prediction interval). [2] It is determined by collecting data from vast numbers of laboratory tests.

  5. Complete blood count - Wikipedia

    en.wikipedia.org/wiki/Complete_blood_count

    A complete blood count (CBC), also known as a full blood count (FBC), is a set of medical laboratory tests that provide information about the cells in a person's blood.The CBC indicates the counts of white blood cells, red blood cells and platelets, the concentration of hemoglobin, and the hematocrit (the volume percentage of red blood cells).

  6. Hematocrit - Wikipedia

    en.wikipedia.org/wiki/Hematocrit

    Typically, a higher hematocrit level signifies the blood sample's ability to transport oxygen, [19] which has led to reports that an "optimal hematocrit level" may exist. Optimal hematocrit levels have been studied through combinations of assays on blood sample's hematocrit itself, viscosity, and hemoglobin level. [19]

  7. Hemorheology - Wikipedia

    en.wikipedia.org/wiki/Hemorheology

    One unit increase in hematocrit can cause up to a 4% increase in blood viscosity. [2] This relationship becomes increasingly sensitive as hematocrit increases. When the hematocrit rises to 60 or 70%, which it often does in polycythemia , [ 4 ] the blood viscosity can become as great as 10 times that of water, and its flow through blood vessels ...

  9. Normocytic anemia - Wikipedia

    en.wikipedia.org/wiki/Normocytic_anemia

    An anemia is normocytic when the red blood cells (RBCs) are of normal size. RBCs are normocytic when the mean corpuscular volume (MCV) is between 80 and 100 femtolitres (fL), which is within the normal and expected range. However, the hematocrit and hemoglobin are decreased. [1]
