Abnormal Red Blood Cells: 2638L Spring 2013, Rotation 9

Front 1

Identify the cell indicated by the arrow.

Back 1

Nucleated Red Blood Cell

Front 2

Give a brief description of Howell Jolly Bodies.

Back 2

Basophilic nuclear remnants seen in young erithrocytes during the response to anemia.

Front 3

Give a brief description of nucleated red blood cells.

Back 3

Immature rbc, represent early release immature cells during anemia.

Front 4

Identify the abnormal RBC indicated by the arrow.

Back 4

Howell Jolly Bodies

Front 5

How would you differentiate between a NRBC and lymphocyte?

Back 5

NRBC: cytoplasm will be similar color to the rbc around it and the nucleus will be darker with looser chromatin structure. Lymphoctyes: sky blue cytoplasm less than in amount than the nrbc.

Front 6

What are some general situations that result in anemia’s?

Back 6

Parasitic infestation and iron-deficiency.

Front 7

What are the 2 classifications of bone marrow response?

Back 7

Nonregenerative and regenerative anemias.

Front 8

How does the retic count relate to the anemia classification?

Back 8

If there are a large amount of retics then more than likely the animal has a regenerative anemia.

Front 9

Give a brief description of Heinz Bodies.

Back 9

Round structures representing denatured hemoglobin caused by certain oxidant drugs or chemicals.

Front 10

Give a brief description of Basophilic stippling.

Back 10

The presence of small, dark blue bodies of residual RNA within the erythrocyte.

Front 11

Identify the abnormal RBC in this photo.

Back 11

Heinz Bodies

Front 12

Identify the abnormal RBC indicated by the arrow.

Back 12

Basophilic stippling

Front 13

Define anemia

Back 13

A decrease in the number of red blood cells (RBCs) or less than the normal quantity of hemoglobin in the blood.

Front 14

Name at least four abnormal red blood cells that would fall under the category, poikilocytes.

Back 14

Acanthocyte, Schistocyte, Keratocyte, Spherocyte, Target Cell, Heinz Bodies, Eccentrocyte, Stomatocyte, Dacrocyte.

Front 15

RBC's with a smaller than normal diameter and decreased MCV; seen in iron deficiency.

Back 15

Microcytes

Front 16

A grouping of erythrocytes in stacks; seen with increased fibrinogen or globulin.

Back 16

Rouleaux

Front 17

Darkly staining red cells with reduced or no central pallor; not easily detected except in dogs; suggest IMHA.

Back 17

Spherocyte

Front 18

Identify the abnormal RBC indicated by the arrows.

Back 18

Target Cell

Front 19

Give a brief description of Agglutination.

Back 19

An antibody coats the erythrocyte causing bridging and clumping.
