  2. Hemoglobinemia - Wikipedia

    en.wikipedia.org/wiki/Hemoglobinemia

    When hemoglobinemia is internally caused, it is a result of recessive genetic defects that cause the red blood cells to lyse, letting the hemoglobin spill out of the cell into the blood plasma. In intravascular hemolysis, hemoglobin is released and binds with haptoglobin. This causes haptoglobin levels to decrease.

  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. Methemoglobinemia - Wikipedia

    en.wikipedia.org/wiki/Methemoglobinemia

    Elevated levels of methemoglobin in the blood are caused when the mechanisms that defend against oxidative stress within the red blood cell are overwhelmed and the oxygen carrying ferrous ion (Fe 2+) of the heme group of the hemoglobin molecule is oxidized to the ferric state (Fe 3+). This converts hemoglobin to methemoglobin, resulting in a ...

    A high reticulocyte count signifies that bone marrow processes are normal. A low reticulocyte count would signify there is a problem at the level of the bone marrow, which produce the stem cells . Acute blood loss would result in a high reticulocyte count, as bone marrow processes are normal and the bone marrow responds accordingly to the body ...

  6. Red blood cell distribution width - Wikipedia

    Deficiencies of Vitamin B 12 or folate produce a macrocytic anemia (large cell anemia) in which the RDW is elevated in roughly two-thirds of all cases. However, a varied size distribution of red blood cells is a hallmark of iron deficiency anemia, and as such shows an increased RDW in virtually all cases.

    en.wikipedia.org/wiki/Hematocrit

    Generally at both sea levels and high altitudes, hematocrit levels rise as children mature. [22] These health-related causes and impacts of elevated hematocrit levels have been reported: Fall in blood plasma levels [5] Dehydration [3] Administering of testosterone supplement therapy [23] [24]

  9. Mean corpuscular hemoglobin concentration - Wikipedia

    en.wikipedia.org/wiki/Mean_corpuscular...

    Hemoglobin. The mean corpuscular hemoglobin concentration (MCHC) is a measure of the concentration of hemoglobin in a given volume of packed red blood cell. It is calculated by dividing the hemoglobin by the hematocrit. Reference ranges for blood tests are 32 to 36 g/dL (320 to 360g/L), [1] or between 4.81 and 5.58 mmol/L.
