While known hematocrit levels are used in detecting conditions, it may fail at times due to hematocrit being the measure of concentration of red blood cells through volume in a blood sample. It does not account for the mass of the red blood cells, and thus the changes in mass can alter a hematocrit level or go undetected while affecting a ...
The primary determinants of blood viscosity are hematocrit, red blood cell deformability, red blood cell aggregation, and plasma viscosity. Plasma's viscosity is determined by water-content and macromolecular components, so these factors that affect blood viscosity are the plasma protein concentration and types of proteins in the plasma.

The changes in shape and flexibility affect the mechanical properties of whole blood. A change in plasma osmotic pressure alters the hematocrit, that is, the volume concentration of red cells in the whole blood by redistributing water between the intravascular and extravascular spaces. This in turn affects the mechanics of the whole blood. [6]
Primary polycythemias are myeloproliferative diseases affecting red blood cell precursors in the bone marrow. Polycythemia vera (PCV) (a.k.a. polycythemia rubra vera (PRV)) occurs when excess red blood cells are produced as a result of an abnormality of the bone marrow. [3] Often, excess white blood cells and platelets are also produced.
Anemia of prematurity is a form of anemia affecting preterm infants [25] with decreased hematocrit. [26] Aplastic anemia: D60-D61: 866: Aplastic anemia is a condition where bone marrow does not produce sufficient new cells to replenish blood cells. [27] Autoimmune hemolytic anemia: D59.0-D59.1
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
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. It is thus a mass or molar ...
The Fåhræus effect (/ f ɑː ˈ r eɪ. ə s /) is the decrease in average concentration of red blood cells in human blood as the diameter of the glass tube in which it is flowing decreases. In other words, in blood vessels with diameters less than 500 micrometers, the hematocrit decreases with decreasing capillary diameter.
