Immune System: Immune System Response and Diagnostic Tests for Infectious Diseases Flashcards
What is the Immune System Response and Diagnostic Tests for Infectious Diseases? (3)
- Most diagnostic tests are based on the humoral immune system’s response to Ag
- Serology the science of detection and measurement of Ab’s or Ag’s
- Various serologic tests have been developed for domestic animals
What do serology tests tell us?
These tests make the Ag/Ab reaction visible to the naked eye if the sample is positive
What are the types of serologic tests for infectious diseases? (3)
- ELISA
- Latex Agglutination
- immunodiffusion
What do the older ELISA tests test for? (4)
- FeLV/FIV
- Giardia
- Heartworm
- Parvo
What do the newer ELISA tests test for? (4)
- Pancreatitis (lipase)
- feline triple
- canine 3Dx
- canine 4Dx
What does the canine 3Dx test for? (3)
- heartworm Ag
- Ehrlichia Ab
- Lyme Ab
What does the canine 4Dx test for? (4)
- heartworm Ag
- Ehrlichia Ab
- Lyme Ab
- Anaplasma Ab
What does the feline triple test for? (3)
- FeLV
- FIV
- Heartworm
What are the Immune System Response and Diagnostic Tests for Infectious Diseases based on and what can they test for?
- antigen-antibody interaction
2. pathogen antigen or host antibody
How are Immune System Response and Diagnostic Tests for Infectious Diseases useful? (2)
- Allows for easy visualization of results
2. In-house tests allow for immediate results
What sample do you need from the animal for Giardia and Parvo tests?
fecal
What are blood tests usually run on? (3)
- whole blood
- serum
- plasma
What do the Snap Heartworm tests detect?
Detects Dirofilaria immitis antigen in feline and canine whole blood, serum, or plasma
What is the Snap Heartworm enzyme immunoassay?
conjugate reacts with reagents in the test device
What will the Snap Heartworm test look like if there is an antigen being detected?
Color development in the antigen spot is proportional to amount of antigen in blood
