Flashcards in Testing and Pathology: Hematologic system Ch 15 Deck (55):
1

blood smear

blood specimen for microscopic examination in which blood is spread thinly across a microscope slide and typically stained

2

bone marrow biopsy

sample of bone marrow obtained by needle aspiration for examination of the cells

3

ultrasound

diagnostic procedure to image the structures of blood vessels (diagnostic ultrasound) and flow of blood through theses vessels (doppler ultrasound).

4

anemia

blood condition of less than normal levels of red blood cells and/or hemoglobin

5

basopenia

deficiency in the number of basophils in the blood

6

-penia

a decrease in a particular type of cell.

7

basophilia

elevation in the number of basophils in the blood

8

philia

an increase in a particular type of cell

9

disseminated intravascular coagulation (DIC)

disorder in which the proteins that control blood clotting become abnormally active, producing clots that obstruct the blood vessels, cut off blood supply to various organs and in time alter the functioning of these organs.

10

dyscarasia

any abnormal condition of the blood

11

edema

accumulation of fluid in the intercellular space

12

edemateous

the adjective form of edema (accumulation of fluid in the intercellular space)

13

eosinopenia

deficiency in the number of eosinophils in the blood

14

eosinophilia

elevation in the number of eosiniphils in the blood

15

erythrocytosis

abnormal increase in red blood cells

16

Cytosis

condition of cell (but implies elevated cell numbers)

17

Exudate

Material that has escaped from blood vessels and is high in protein, cells, or solid materials derived from cells (typically inflammatory in nature).

18

Hemolytic

Removing and destroying red blood cells

19

Hemolytic Anemia

Excessive RBC destruction that results in lower than normal levels of RBCs

20

Hemolytic Serum

Contains red blood cell components that are released when erythrocytes are damaged due to a variety of causes (improper specimen processing, collection or transport)

21

Hemolysis

Breakdown of red blood cells

22

Lysis

Destruction or breakdown

23

Hemophilia

Hereditary condition of deficient blood coagulation

24

Hemorrhage

Loss of blood (usually over a short period of time)

25

Hemostasis

The act of controlling blood or bleeding

26

Hemostat

An instrument used to control bleeding

27

hyperalbuminemia

Blood condition of abnormally high albumin levels

28

Hyperemia

Excess blood in a part; engorgement

29

Hyperlipidemia

Blood concentration of abnormally high fat levels (caused by fat metabolism)

30

Lip/o

fat

31

Icteric Serum

Serum that has yellow pigmentation that is suggestive of hyperbilirubinemia (increased bilirubin levels)

32

Lipemic Serum

Contains excess amount of fat and appears white

33

Left Shift

an alteration in the distribution of leukocytes in which there are increases in banded neutrophils usually in response to severe bacterial infection.

34

Leukemia

Elevation in the number of malignant white blood cells (animals with leukemia have a very high WBC count) - classified by concentration of neoplastic cells circulating in blood (acute or chronic)

35

Leukocytosis

elevation in number of white blood cells

36

Leukopenia or Leukocytopenia

Deficiency of white blood cells

37

Lipemia

Excessive amounts of fats in blood

38

Lymphocytosis

elevated number of lymphocytes in the blood

39

Modified transudate

Material that has cell numbers and distribution similar to transudates but the protein concentration is greater than 2.5 g/dL resulting from leakage of high protein lymph or occasionally inflammatory proteins (modified transudates are common in right sided heart failure)

40

Monocytopenia

Deficiency of monocytes in the blood

41

Monocytosis

Elevated number of monocytes in the blood

42

Myelodysplasia

Hematologic disorder characterized clinically and morphologically by ineffective hematopoiesis that results in some form of cytopenia such as anemia, neutropenia, and/or thrombocytopenia

43

Neutropenia

Deficiency in the number of neutrophils in the blood

44

Neutrophilia

Elevation in the number of neutrophils in the blood

45

Pancytopenia

Deficiency of all types of blood cells

46

Phagocytosis

Condition of engulfing or eating cells

47

Polycythemia

Condition of many cells (excessive erythrocytes)

48

Septicemia

Blood condition in which pathogenic microorganisms (bacteria) and their toxins are present.

49

Emia

Blood condition

50

Pathogenic

Producing disease

51

Bacteremia

Blood condition in which bacteria are present

52

Thrombocytopenia

Abnormal decrease in the number of clotting cells

53

Penia

less than normal or deficiency

54

Thrombocytosis

Elevation in the number of clotting cells

55

Transudate

Material that has passed through a membrane and is high in fluidity and low in protein, cells, or solid materials derived from cells. (Observed with Hepatic disease, protein losing enteropathy or protein losing nephropathy)
