Blood smear examination is usually performed in conjunction with a complete blood count in order to investigate abnormal results or confirm results that the automated analyzer has flagged as unreliable. [3] Microscopic examination of the shape, size, and coloration of red blood cells is useful for determining the cause of anemia.
Acanthocytes, from peripheral blood, under light microscopy. Note the irregularly shaped, non-circular cells in the image. Acanthocyte (from the Greek word ἄκανθα acantha, meaning 'thorn'), in biology and medicine, refers to an abnormal form of red blood cell that has a spiked cell membrane, due to thorny projections.
On routine smear morphology, some people like to make a distinction between leptocytes and codocytes- suggesting that in leptocytes the central spot is not completely detached from the peripheral ring, i.e. the pallor is in a C shape rather than a full ring.
Rare elliptocytes (less than 1%) on a peripheral blood smear are a normal finding. [citation needed] These abnormal red blood cells are seen in higher numbers in the blood films of patients with blood disorders such as: [4] Hereditary elliptocytosis and Southeast Asian ovalocytosis; Thalassemia; Iron deficiency; Myelodysplastic syndrome and ...
Stomatocyte compared to other forms of poikilocytosis.. Hereditary stomatocytosis describes a number of inherited, mostly autosomal dominant human conditions which affect the red blood cell and create the appearance of a slit-like area of central pallor (stomatocyte) among erythrocytes on peripheral blood smear.
The white blood cell differential is a common blood test that is often ordered alongside a complete blood count.The test may be performed as part of a routine medical examination; to investigate certain symptoms, particularly those suggestive of infection or hematological disorders; [5] [6] or to monitor existing conditions, such as blood disorders and inflammatory diseases.
Upon examination of a peripheral blood smear under microscope, these macrocytes appear larger than standard erythrocytes. Macrocytosis is a common morphological feature in neonatal peripheral blood. [3] The presence of macrocytosis can indicate a range of conditions, from benign, treatable illnesses to more serious underlying disorders.
The diagnosis of hereditary elliptocytosis is usually made by coupling a family history of the condition with an appropriate clinical presentation and confirmation on a blood smear. In general it requires that at least 25% of erythrocytes in the specimen are abnormally elliptical in shape, though the observed percentage of elliptocytes can be 100%.
