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]
Neutropenia is an abnormally low concentration of neutrophils (a type of white blood cell) in the blood. [4] Neutrophils make up the majority of circulating white blood cells and serve as the primary defense against infections by destroying bacteria, bacterial fragments and immunoglobulin-bound viruses in the blood. [5]
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 scanning electron microscope image of normal circulating human blood. One can see red blood cells, several knobby white blood cells including lymphocytes, a monocyte, a neutrophil, and many small disc-shape platelets. White blood cells (WBCs) are also known as leukocytes. Most leukocytes differ from other cells of the body in that they are ...
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 ...
Megaloblastic anemia caused by vitamin B 12 deficiency is characterized by red blood cells that are larger than normal and are unable to deliver oxygen to the body's organs. [7] [8] The clinical case indicates an altered synthesis of DNA, in which vitamin B 12 is essential for the production and maturation of red blood cells in the bone marrow. [8]

Blood cell counts: Deviations in specific blood cells can point to an immune system anomaly. Immune system cells: These assessments are used to measure the levels of various immune cells. Genetic testing involves collecting samples from patients for molecular analysis when there is a suspicion of inborn errors in immunity.
