Flashcards in Chapter 15 Diagnostic Techniques Deck (82)
Which term means "the determination of the nature and cause of a disease, injury, or congenital defect"?
Which term means "to predict the outcome of a disease"?
Where are endoparasites most commonly found in laboratory animals?
In the intestinal tract
What samples can be used to find endoparasites in the body?
Which test is a quick method, though not very accurate, for detecting endoparasites?
Direct fecal smear
What signs might be an indication that an animal has ectoparasites?
Testing with a fecal analysis kit does not require centrifugation.
Direct smear is the primary method used to detect protozoan parasites in an animal
Ectoparasites leave a dead body as it cools.
By which method are most endoparasites detected?
Fecal flotation is used to determine if and/or are present in the sample
Parasite eggs; coccidial oocytes
Mites in fur samples are visible by eye.
To detect endoparasites by fecal flotation, sugar may be mixed with the fecal specimen.
Serological tests are used to determine the type of organisms present in a skin scraping sample.
False: PCR is used to determine the type of organisms present in a skin scraping sample.
The fecal flotation test requires a larger sample than the one needed for the direct smear.
An animal may need to be sedated to swab its ear to check for ear mites.
PCR is more sensitive than a tape test for the detection of pinworm species
Hematology can assist in the diagnosis of what health problems:
Lymphocyctes are produced by the:
A white blood cell count includes quantification for all types of white blood cells.
What function is served by basophils?
Initiation of inflammatory response.
Hemoglobin is the:
oxygen-carrying component of red blood cells
A hematocrit is used to determine:
packed cell volume
What best describes plasma?
The liquid portion of unclotted blood
What test provides information on blood cell morphology?
Peripheral blood smear
In most species, which type of white blood cells are most numerous?
The neutrophil to lymphocyte ratio varies among healthy animals of different species.
The enzyme-linked immunosorbent assay (ELISA) is a test used to quantify antibodies or antigens in the research laboratory.
Serology is testing of serum for the presence or absence of:
