inclusion
Heinz bodies are most commonly oval or
round.
A mature erythrocyte containing siderotic granules is referred to as a
siderocyte,
Howell-Jolly bodies can be observed on a Wright-stained peripheral blood smear post
splenectomy or when spleen is not working properly
Heinz bodies do not appear on a peripheral blood smear stained with a Wright or Wright-Giemsa-stain. A
supravital stain, such as brilliant green, crystal violet, or new methylene blue is necessary for Heinz bodies to be observed.
The presence of erythrocyte inclusions may indicate the presence of disease.
true
Cabot rings appear as thin, red-
violet-staining strands in the shape of rings, figure eights,
reticulocyte
ribosome
siderotic granules form
ring around the nucleus
If present, how many Howell-Jolly bodies are usually seen within a given erythrocyte?
1
What is the composition of the granules associated with basophilic stippling?
Aggregates of ribosomes
This image represents a field of red blood cells (RBCs) that were stained using a supravital stain. How would these cells appear if they were viewed on a Wright stained smear?
Polychromatophilic RBCs
Heinz bodies are composed of which of the following?
Denatured hemoglobin
Heinz bodies can be found in which of the following disorders?
G6PD deficiency
Siderotic Granules To verify that red cell inclusions contain iron, it is necessary to use an iron stain,
Prussian blue.
In which of the following conditions would you expect to find Howell-Jolly bodies?
Hyposplenism (low functioning spleen)
In which of the following conditions might Cabot rings be observed in erythrocytes on a Wright-stained peripheral blood smear?
oderate iron deficiency anemia and megaloblastic anemia
Which of the following statements characterize a reticulocyte?
Its reticulum is visible with a supravital stain, such as new methylene blue.
Pappenheimer bodies are also seen
peripheral blood following a splenectomy
Which of the following is NOT present in normal bone marrow and would be associated with a disease or disorder?
Ringed sideroblast
In which of the following disorders would you probably observe coarse basophilic stippling on a Wright-stained peripheral blood smear?
Thalassemia and lead poisoning
Howell-Jolly bodies
presence of megaloblastic anemia or abnormal erythropoiesis.hemolytic anemias, thalassemia, and sickle cell anemia.
Howell jolly bodies
These RBC inclusions contain DNA.
hich of the following statements best describes the appearance of Cabot rings
Thin, reddish-violet-staining strands in the shapes of rings, figure eights, or the letter B
polychromatophilic RBCs
blue-gray appearance when compared to the other RBCs in the field.
Reticulocytes appear
blue-gray on the Wright or Wright-Giemsa-stained smear and are referred to as polychromatophilic red cells
Pappenheimer bodies
by an increase in the storage of iron, such as sideroblastic anemia and thalassemia
The basophilic stippling that is clinically significant is referred to as
coarse stippling
Heinz bodies are commonly associated with
glucose-6-phosphate dehydrogenase (G6PD) deficiency and other red cell enzyme disorders.
Pappenheimer bodies, while visible on a Wright's stained smear, should be confirmed with
iron stain, such as Prussian blue stain.
2 or more can be seen on the holly
jolly bodies
Cabot rings have been observed in
megaloblastic anemia, lead poisoning, severe anemia, leukemia, myelodysplastic syndromes, and other cases of dyserythropoiesis.
