The anticonvulsant drug, lamotrigine, has been associated with a decrease in white blood cell count. [2] The FDA monograph for metronidazole states that this medication can also cause leukopenia, and the prescriber information suggests a complete blood count, including differential cell count, before and after, in particular, high-dose therapy. [3]
An anemia is a decrease in number of red blood cells (RBCs) or less than the normal quantity of hemoglobin in the blood. [2] [3] However, it can include decreased oxygen-binding ability of each hemoglobin molecule due to deformity or lack in numerical development as in some other types of hemoglobin deficiency.
A strict but broad definition is an absolute decrease in red blood cell mass, [61] however, a broader definition is a lowered ability of the blood to carry oxygen. [62] 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 .
A blood smear showing hypochromic (and microcytic) anemia. Note the increased central pallor of the red blood cells. Hypochromic anemia is a generic term for any type of anemia in which the red blood cells are paler than normal. (Hypo- refers to less, and chromic means colour.) A normal red blood cell has a biconcave disk shape and will have an ...
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 ...

Aplastic anemia [2] (AA) [3] is a severe hematologic condition in which the body fails to make blood cells in sufficient numbers. Blood cells are produced in the bone marrow by stem cells that reside there. [4] Aplastic anemia causes a deficiency of all blood cell types: red blood cells, white blood cells, and platelets. [5] [6]
If the anemia is due to iron deficiency, one of the first abnormal values to be noted on a complete blood count, as the body's iron stores begin to be depleted, will be a high red blood cell distribution width, reflecting an increased variability in the size of red blood cells. [15] [23] A low mean corpuscular volume also appears during the ...
