The presence of Heinz bodies represents damage to hemoglobin and is classically observed in G6PD deficiency, a genetic disorder that causes hemolytic anemia. In veterinary medicine, Heinz bodies may be seen following the consumption of foods containing thiosulfate and propylene glycol compounds by cats, dogs and certain primates.
However, if a large number of Heinz bodies are produced, as in the case of G6PD deficiency, some Heinz bodies will nonetheless be visible when viewing RBCs that have been stained with crystal violet. This easy and inexpensive test can lead to an initial presumption of G6PD deficiency, which can be confirmed with the other tests. [citation needed]
A degmacyte or bite cell is an abnormally shaped mature red blood cell with one or more semicircular portions removed from the cell margin, known as "bites". [1] [2] These "bites" result from the mechanical removal of denatured hemoglobin during splenic filtration as red cells attempt to migrate through endothelial slits from splenic cords into the splenic sinuses.

Heinz bodies form in the cytoplasm of RBCs and appear as small dark dots under the microscope. In animals, Heinz body anemia has many causes. In animals, Heinz body anemia has many causes. It may be drug-induced, for example in cats and dogs by acetaminophen (paracetamol), [ 84 ] or may be caused by eating various plants or other substances:
Hemichrome formation, followed by a band 3 clustering and the formation of Heinz bodies, can take place during the physiological clearance of damaged red blood cells. [4] The difference between a normal red blood cell (RBC) and a red blood cell with unstable hemoglobin (such as in the case of hemolytic anaemia ) is that, in a normal RBC, the ...
Splenectomy patients typically have Howell-Jolly bodies [11] [12] and less commonly Heinz bodies in their blood smears. [13] Heinz bodies are usually found in cases of G6PD (Glucose-6-Phosphate Dehydrogenase) and chronic liver disease. [14] A splenectomy also results in a greatly diminished frequency of memory B cells. [15]
Heinz sparked backlash for perpetuating racial bias against Black people after releasing two different controversial ads. After facing significant criticism for seemingly erasing Black fathers ...
Blood smear showing red blood cells with basophilic stippling. Basophilic stippling, also known as punctate basophilia, is the presence of numerous basophilic granules that are dispersed through the cytoplasm of erythrocytes in a peripheral blood smear.
