CHAPTER 1 Flashcards
- deals with the diagnosis of disease by laboratory means
- It involves the collection and examination of body fluids and interpretations of laboratory findings. It is applied in both animals and humans.
Clinical Pathology
It supports the diagnosis of disease using laboratory testing of blood and other bodily fluids, tissues, and microscopic evaluation of individual cells.

The most commonly used site in the horse, cattle, sheep, goat, camel
and large wild mammals: used occasionally in small animals
Jugular vein

Cephalic vein - The most commonly used site for collection of small amount of blood in what animal?
dog
The most commonly used site for collection of small amount of blood in the dog. By constricting the area on the
dorsal aspects of the fore limb at the level of the elbow which can be raised beginning just above the carpal vein.
Cephalic vein
can be used in small dog, pig, cat and small lab animals (small dog, rabbit, guinea pig, and monkey). A marginal vein
on the dorsal side of the ear is selected
Ear vein

In ear vein, this type of vein is used for blood collection located
on the dorsal side of the ear is selected
