anisocytosis การใช้

• An elevated RDW ( red blood cells of unequal sizes ) is known as anisocytosis.
• In practice though elliptocytes and anisocytosis are often seen in thalessemia and target cells occasionally in iron deficiency.
• Anemia of chronic disease shows unremarkable RBCs, iron deficiency shows anisocytosis, anisochromia and elliptocytosis, and thalessemias demonstrate target cells and coarse basophilic stippling.
• The red cell distribution width ( RDW ) is a measurement of anisocytosis and is calculated as a coefficient of variation of the distribution of RBC volumes divided by the mean corpuscular volume ( MCV)
• The blood smear of a person with iron deficiency shows many hypochromic ( pale and relatively colorless ) and rather small RBCs, and may also show poikilocytosis ( variation in shape ) and anisocytosis ( variation in size ).
