	Complete blood count - Wikipedia, the free encyclopedia
		The cells that circulate in the bloodstream are generally divided into three types: white blood cells (leukocytes), red blood cells (erythrocytes), and platelets or thrombocytes.
		In the past, counting the cells in a patient's blood was performed manually, by viewing a slide prepared with a sample of the patient's blood under a microscope (a blood film, or peripheral smear).
		Mean cell hemoglobin concentration (MCHC) - the average concentration of hemoglobin in the cells.

	Mean cell hemoglobin concentration definition - Medical Dictionary definitions of popular medical terms
		Mean cell hemoglobin concentration: The average concentration of hemoglobin in a given volume of blood.
		The MCHC is a calculated value derived from the measurement of hemoglobin and the hematocrit.
		(The hemoglobin value is the amount of hemoglobin in a volume of blood while the hematocrit is the ratio of the volume of red cells to the volume of whole blood.) The normal range for the MCHC is 32 - 36%.

	Sickle Cell Review for clinicians
		Sickle cell diseases are a group of inherited hemoglobin disorders characterized by chronic hemolytic anemia, a heightened susceptibility to infections, end-organ damage, and intermittent episodes of vascular occlusion causing both acute and chronic pain.
		The factors that favor sickle cell formation include deoxygenation of the hemoglobin molecule, increased percentage of Hb S in the red blood cell, increased mean cell hemoglobin concentration which is a function of red cell hydration, low pH, and increased temperature, and blood stasis.
		During sequestration episodes sickle cells are trapped in the spleen, causing rapid fall in the hemoglobin level and enlargement of the spleen.

		Hemoglobin is the protein molecule within red blood cells that carries oxygen and gives blood its red color.
		Normal range for hemoglobin is different between the sexes and is approximately 13 - 18 grams per deciliter for men and 12 - 16 for women (international units 8.1 - 11.2 millimoles/liter for men, 7.4 - 9.9 for women).
		This is a calculated volume derived from the hemoglobin measurement and the hematocrit.

		Mean cell hemoglobin: The average amount of hemoglobin in the average red cell.
		The mean cell hemoglobin (MCH) is a calculated value derived from the measurement of hemoglobin and the red cell count.
		(The hemoglobin value is the amount of hemoglobin in a volume of blood while the red cell count is the number of red blood cells in a volume of blood.) The normal range for the MCH is 27 - 32 picograms.

	NORMAL REFERENCE VALUES FOR HEMATOLOGICAL PARAMETERS,
		The objective of this study was to determine the values of hematological parameters, red cell indices and Hb A2 and Hb F levels in normal Saudi children, living in the Central province of Saudi Arabia.
		Hematological parameters, red cell indices, and hemoglobin types (Hb A2 and Hb F) were estimated, and the children were divided into 15 groups depending on the age.
		Mean cell volume and mean cell hemoglobin also showed slight increases, while mean cell hemoglobin concentration remained more or less constant.

	Phenotypic Variability in Sickle Cell Disease
		Fetal hemoglobin, as its name implies is the primary hemoglobin present in the fetus from mid to late gestation (Higgs et al, 1989).
		These cells would be prone to sickling, and could occlude the microcirculation, blocking the flow of cells that normally might have made it across the circulatory narrows.
		Reduction in overall hemoglobin concentration due to absent alpha genes is not the only mechanism by which alpha-thalassemia reduces the formation of dense and irreversibly sickled cells.

	TKAS -- Lebelo et al. (2001)
		White blood cell counts (WBCC) were determined by diluting the blood with Shaw's fluid (1:20) in a standard white blood cell pipette (Shaw, 1930) and the same procedure was followed as for the red blood cell count (Shaw, 1930; Hesser, 1960).
		An additional explanation for the inability to show a significant change in packed cell volumes between the hypoxic group and healthy fish may have been the use of MS 222 as an anesthetic and heart puncture as a means for obtaining blood.
		The effect of increased packed cell volume on apparent blood viscosity, as occurred in the disease group, was determined by comparing the apparent blood viscosity of the diseased group at its original mean packed cell volume of 40% to healthy striped bass at their mean packed cell volume of 30%.

		Hemoglobin concentration is a more precise term than hemoglobin since the amount of hemoglobin per unit volume (L) is measured.
		Hematocrit is measured by the direct reading of a blood-filled tube that has previously been centrifuged, or it is calculated from the hemoglobin by an electronic cell counting device.
		The MCH classifies hypochromic (iron deficiency anemia, thalassemia) and normochromic (anemia of chronic disorders, anemia of renal disease).

		The amount of hemoglobin in the cell increases proportionately, so the mean cell hemoglobin concentration (MCHC) remains within normal limits.
		Patients with hepatic disease and obstructive jaundice have a macrocytosis that is secondary to increased cholesterol and/or phospholipids deposited on the membranes of circulating RBCs.
		The macrocytosis associated with COPD is attributed to excess cell water that is secondary to carbon dioxide retention.

	Diagnose-Me: Condition: A High White Count
		The white blood cell count is done routinely as part of a complete blood count and further studies are usually needed if abnormalities are discovered through this test.
		However, a low white blood cell count will make an individual susceptible to infectious diseases or allow multiplication of organisms within the body which are normally kept in check by the immune system.
		White blood cells are composed primarily of neutrophils, monocytes and lymphocytes.

	Phenotypic Variability in Sickle Cell Disease
		People with sickle cell trait would have a better chance of surviving an outbreak of malaria and passing their genes (for sickle and normal hemoglobin) to the next generation when they have children.
		In contrast, splenomegaly is common in patients with sickle cell disease in India, while the spleens of most patients in the Americas are small and poorly functional (due to recurrent splenic infarctions).
		Sickle cell disease in India exists mainly in the tribal populations, who to this day remain relatively isolated from the country's mainstream society.

		In addition, a CBC may include a red cell distribution width (RDW), mean platelet volume (MPV) and a differential exam of the quality and quantity of white blood cells, notes the ASCLS.
		While simply counting cells doesn’t fully describe their quality, these tests are more descriptive of the red blood cell population.
		For instance, an MCV of 90 could signify that all of the patient’s cells are 90 femtoliters in volume, or it could suggest a range between 85 and 95.

		Hemoglobin is a large complex protein made up of globin chains and heme found inside the red cells.
		When looking at red cells, it is the hemoglobin that gives the cell its red color so less than adequate hemoglobin is known as hypochromia.
		Cells whose granules stain bright red orange are called eosinophils and are part of the allergic response.

		The hemoglobin concentration is probably the most accurate (and the red cell count the least accurate) of the three analytes needed to calculate the red cell indices.
		That is to say, the hemoglobin multiplied by 3 should approximate the hematocrit or the hematocrit divided by 3 should approximate the hemoglobin.
		For example a buffy coat that is 3% of the microhematocrit tube represents a 50,000 white blood cell count/µl, 10,000 cells from the first percent and 20,000 cells for each of the remaining two percents.

		One hospital spins a hematocrit and then manually replaces all hemoglobin parameters, such as hemoglobin, mean corpuscular hemoglobin, and mean corpuscular hemoglobin count, with asterisks so those results are unavailable.
		Lipemia interferes with the accurate determination of hemoglobin, or Hb, by spectroscopy on most hematology analyzers, but it does not generally interfere with determinations (especially impedance based) of red blood cell count, white blood cell count, and platelet count.
		Since hematology analyzers measure mean cell volume, RBC, and Hb, and determine hematocrit, mean cell hemoglobin, and mean cell hemoglobin concentration, an inaccurate Hb affects the hematology result and those derived from it.
