Red blood cell indices are blood tests that provide information about the hemoglobin content and size of red blood cells. Abnormal values indicate the presence of anemia and which type of anemia it is.
The fraction of red blood cells in the tube was measured after centrifugation to determine the hematocrit. The invention of a reproducible method for determining hematocrit values allowed Wintrobe to define the red blood cell indices. [205] Model A Coulter counter. Research into automated cell counting began in the early 20th century. [211]
The index is calculated from the results of a complete blood count. If the quotient of the mean corpuscular volume (MCV, in fL) divided by the red blood cell count (RBC, in million per microliter) is less than 13, β-thalassemia trait is said to be more likely. If the result is greater than 13, then iron-deficiency anemia is said to be more likely.
Red blood cells have an average volume of 80–100 femtoliters, but individual cell volumes vary even in healthy blood. [1] Certain disorders, however, cause a significantly increased variation in cell size. Higher RDW values indicate greater variation in size. Normal reference range of RDW-CV in human red blood cells is 11.5–15.4%.
In a CBC, there's three main indicators of how much red blood cell action you have: red blood cell count (RBC), hemoglobin (HGV) and hematocrit (HCT). In general, these indicators all have ...
The mean corpuscular hemoglobin concentration (MCHC) is a measure of the concentration of hemoglobin in a given volume of packed red blood cell. It is calculated by dividing the hemoglobin by the hematocrit. Reference ranges for blood tests are 32 to 36 g/dL (320 to 360g/L), [1] or between 4.81 and 5.58 mmol/L.

Spur cell hemolytic anemia is a form of hemolytic anemia that results when free cholesterol binds to the red blood cell's membrane increasing its surface area, causing later deformities such as rough or thorny projections on the erythrocyte named acanthocytes. This condition is caused by the deceased liver's decreased ability to esterificate ...
