25
2 methods of tissue biopsy
Wedge and punch
26
Tissue biopsy sample is obtained with a scalpel blade | Used for solitary lesions
Wedge
27
Tissue biopsy sample is obtained with a punch tool | Quick and easy to do
Punch
28
Most common type of punch biopsy
Keyes
29
Biopsy samples should be placed in _________ within one minute of obtaining and should be allowed to preserve for ___ hrs
formalin; 24
30
You should not ________ a tissue sample
freeze
31
Introduction of a needle into a body cavity or organ to remove fluid
Centesis
32
Done in the peritoneal cavity
Abdominocentesis/parecentesis
33
Done in the thoracic/pleural cavity
Thoracocentesis
34
Done in the bladder
Cystocentesis
35
To obtain CSF
CSF tap
36
Taken from within a joint space
Arthrocentesis
37
To obtain aqueous or vitreous humor
Eye centesis
38
Cytological evaluation of mucus samples obtained from the trachea, bronchi, or bronchioles to assist with diagnosing pulmonary disease
Transtracheal/Bronchial wash
39
3 techniques to a transtracheal/bronchial wash
1. Percutaneous 2. orotracheal 3. bronchoalveolar
40
Area is injected with lidocaine, jugular catheter is placed in the trachea and flushed with saline, when the animal coughs retract plunger and collect sample
Percutaneous
41
Requires light anesthesia and placement of an endotracheal tube Urinary/jugular catheter is placed through endotracheal tube and flushed with saline. Animal may not cough, so the sample should be collected after a few seconds
Orotracheal
42
Bronchoscope is needed and samples are collected to assess lower respiratory tract
Bronchoalveolar
43
Remember to collect ___ fluid expelled when an animal coughs and put into a red top tube
ALL
44
This aids in the diagnosis of upper airway diseases Normal saline is infused into the nasal cavity using a syringe and tubing; sample is aspirated Helps diagnose inflammation secondary to sepsis, fungi, yeast, and neoplasm
Nasal flush
45
A fluid that is colorless, low specific gravity, low protein, little to no RBCs, 95-100% lymphocytes
CSF
46
A fluid that is colorless to straw yellow, transparent to slightly cloudy, odorless, and low TP
Peritoneal fluid
47
A fluid that is due to a ruptured mass where blood leaks into the peritoneal cavity
Hemoabdomen
48
A fluid that is pulled in a thoracocentesis. It is milky white and contains a large amount of fats and some lymphocytes
Chylous effusion
49
Viscosity should be observed by performing a mucin clot test | Should be thick
Synovial fluid
50
Large amounts of mucus are found in this fluid
Tracheal wash
51
How many slides should be made from a fluid sample?
Multiple
52
Fluid samples should be placed in
EDTA tubes
53
All fluid placed on slide should remain on slide and not spread off the edge
Edge of Cliff syndrome
54
The preferred fixative for cytological evaluation
95% methanol
55
2 general types of stains used for cytology
1. Romanowsky | 2. New Methyelene blue
56
3 Romanowsky stains
1. Diff Quick!!!! 2. Giemsa 3. Wright's
57
Used as an adjunct to Romanowsky stain
NMB
58
These are inexpensive, readily available, easy to prepare, maintain, and use
Romanowsky stain
59
Bone marrow and lymph node samples should set in Diff quik for how long?
1-2 minutes
60
This stain stains the cytoplasm weakly but gives excellent nucleolar details Used for nucleated cells, most infectious agents, platelets, bacteria, fungi, yeast, and mast cell granules

61
Detects the presence of bacteria
Gram stain
62
Gram negative
red/pink stain
63
Gram positive
purple
64
Used for histological evaluations
Hematoxin/Eosin stain
65
Commonly used with human gynecological exams because it provides good nuclear detail

67
Made with commercially available cover slip mounting glue
Permanent mount
