Abnormal red blood cell (erythrocyte) with a ringed appearance; associated with several types of anemia.
An abnormal form of red blood cell (erythrocyte) in which the cell assumes the ringed appearance of a ‘target’ in stained blood films. Target cells are a feature of several types of anemia, including those due to iron deficiency and abnormalities in hemoglobin structure.
The specific organ or tissue upon which a hormone, drug, or other substance acts.
Abnormal erythrocytes Rack are large and ‘floppy’ and have a ringed appearance, similar to that of a target, when stained and viewed under the microscope. This change from normal may occur with iron-deficiency anaemia, liver disease, a small spleen, haemoglobinopathies (disorders of haemoglobin), and thalassaemia.
An erythrocyte with a dark rounded central area surrounded by a lightly stained clear ring, which in turn is surrounded by a dense ring of peripheral cytoplasm. It is present in certain blood disorders, such as thalassemia, and in patients who have no spleen.
