  2. Red blood cell distribution width - Wikipedia

    en.wikipedia.org/wiki/Red_blood_cell...

    RDW-SD is calculated as the width (in fL) of the RBC size distribution histogram at the 20% height level. This parameter is, therefore, not influenced by the average RBC size (mean corpuscular volume, MCV). [7] RDW-CV (expressed in %) is calculated with the following formula: RDW-CV = (1 standard deviation of RBC volume ÷ MCV) × 100%. [8]

  3. Hemoglobin - Wikipedia

    en.wikipedia.org/wiki/Hemoglobin

    Hemoglobin's binding affinity for CO is 250 times greater than its affinity for oxygen, [69] [70] Since carbon monoxide is a colorless, odorless and tasteless gas, and poses a potentially fatal threat, carbon monoxide detectors have become commercially available to warn of dangerous levels in residences. When hemoglobin combines with CO, it ...

  4. Glycated hemoglobin - Wikipedia

    en.wikipedia.org/wiki/Glycated_hemoglobin

    When blood glucose levels are high, glucose molecules attach to the hemoglobin in red blood cells. The longer hyperglycemia occurs in blood, the more glucose binds to hemoglobin in the red blood cells and the higher the glycated hemoglobin. [17] Once a hemoglobin molecule is glycated, it remains that way.

  5. Blood sugar level - Wikipedia

    en.wikipedia.org/wiki/Blood_sugar_level

    This method measures the level of glycated hemoglobin, which is representative of the average blood glucose levels over the last, approximately, 120 days. [ 36 ] In either case, the chemical system is commonly contained on a test strip which is inserted into a meter, and then has a blood sample applied.

  6. Pernicious anemia - Wikipedia

    en.wikipedia.org/wiki/Pernicious_anemia

    Pernicious anemia is a disease where not enough red blood cells are produced due to a deficiency of vitamin B 12. [5] Those affected often have a gradual onset. [5] The most common initial symptoms are feeling tired and weak. [4]

    On Saturday, Francis developed a low platelet count, which remained low but stable Sunday. Platelets are cell-like fragments that circulate in the blood that help form blood clots to stop bleeding or help wounds heal. Low platelet counts can be caused by a number of things, including side effects from medicines or infections.

  8. Anemia - Wikipedia

    en.wikipedia.org/wiki/Anemia

    Iron is an essential part of hemoglobin, and low iron levels result in decreased incorporation of hemoglobin into red blood cells. In the United States, 12% of all women of childbearing age have iron deficiency, compared with only 2% of adult men.

  9. Iron-deficiency anemia - Wikipedia

    en.wikipedia.org/wiki/Iron-deficiency_anemia

    Iron-deficiency anemia is anemia caused by a lack of iron. [3] Anemia is defined as a decrease in the number of red blood cells or the amount of hemoglobin in the blood. [3] When onset is slow, symptoms are often vague such as feeling tired, weak, short of breath, or having decreased ability to exercise. [1]
