Polychromatic red blood cells appear bluish-gray on the blood smear. Polychromasia is a disorder where there is an abnormally high number of immature red blood cells found in the bloodstream as a result of being prematurely released from the bone marrow during blood formation ( poly - refers to many , and -chromasia means color .)
A complete blood count (CBC), also known as a full blood count (FBC), is a set of medical laboratory tests that provide information about the cells in a person's blood.The CBC indicates the counts of white blood cells, red blood cells and platelets, the concentration of hemoglobin, and the hematocrit (the volume percentage of red blood cells).
Normocytic anemia is a type of anemia and is a common issue that occurs for men and women typically over 85 years old. Its prevalence increases with age, reaching 44 percent in men older than 85 years. [1] The most common type of normocytic anemia is anemia of chronic disease. [1]
Research shows men are more likely than women to avoid—or delay—necessary medical care, even when their symptoms disrupt their lives or become chronic. An online survey conducted by the ...
Red blood cell distribution width (RDW or RDW-CV or RCDW and RDW-SD) is a measure of the range of variation of red blood cell (RBC) volume, yielding clues about morphology. [ citation needed ] Erythropoietic precursor indices

The normal erythrocyte volume in humans is about 80 to 100 femtoliters (fL= 10 −15 L). In metric terms the size is given in equivalent cubic micrometers (1 μm 3 = 1 fL). The condition of having erythrocytes which (on average) are too large, is called macrocytosis. In contrast, in microcytic anemia, the erythrocytes are smaller than normal.
In a healthy person, a red blood cell survives 90 to 120 days in the circulation, so about 1% of human red blood cells break down each day. [ 38 ] [ unreliable medical source? ] The spleen (part of the reticulo-endothelial system ) is the main organ that removes old and damaged RBCs from the circulation. [ 2 ]
