Mean corpuscular hemoglobin concentration (MCHC) is the average concentration of hemoglobin per unit volume of red blood cells and is calculated by dividing the hemoglobin by the hematocrit. [citation needed] = Normal range: 32-36 g/dL
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]
Red blood cells (RBCs), referred to as erythrocytes (from Ancient Greek erythros 'red' and kytos 'hollow vessel', with -cyte translated as 'cell' in modern usage) in academia and medical publishing, also known as red cells, [1] erythroid cells, and rarely haematids, are the most common type of blood cell and the vertebrate's principal means of delivering oxygen (O 2) to the body tissues—via ...
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. The incidence is as high as 20% among African American and Mexican American women.

Glycated hemoglobin (also called glycohemoglobin) is a form of hemoglobin (Hb) that is chemically linked to a sugar. ("Glycosylated haemoglobin" is a misnomer because glycation and glycosylation are different processes, of which only the former is relevant in this case; glycation is non-enzymatic, while glycosylation is enzymatic.)
The global mean fasting plasma blood glucose level in humans is about 5.5 mmol/L (100 mg/dL); [11] [12] however, this level fluctuates throughout the day. Blood sugar levels for those without diabetes and who are not fasting should be below 6.9 mmol/L (125 mg/dL).
In cases of hemorrhagic shock, hematocrit and hemoglobin can be severely decreased. However, with a reduction in plasma volume, hematocrit and hemoglobin can be increased due to hemoconcentration. [4] Low urinary sodium is commonly found in hypovolemic patients as the kidneys attempt to conserve sodium and water to expand the extracellular volume.
Hemoglobin analysis, with tests such as high-performance liquid chromatography, along with genetic testing are required for the confirmation of Hb H disease. [ 6 ] [ 7 ] Patients may also laboratory abnormalities indicative of low red blood cells, including changes in hemoglobin, red cell distribution width , hematocrit , mean corpuscular ...
