4 Examples of Humoral Immunity Tests
ELISA - Enzyme Linked Immunosrobent Assay
Latex Agglutination
Immunodiffusion
Rapid Immunomigration
List an Example of a Cell Mediated Immunity Test.
Tuberculin Skin Test
List another uncategorized test.
PCR - Polymerase Chain Reaction
How does an ELISA test work?
Binds antigen / antibody complexes together, amplifying the connection and exhibiting results via a color change
What kind of ELISA tests are available? (7)
Lyme Disease
Leptospirosis
Heart worm Disease
FeLV / FIV
Pancreatitis
Giardia
Parvovirus
What is the most common test that uses the Latex Agglutination Technique?
Blood Typing Cards
When doing a blood typing card, what will happen if the blood has antibodies to the antigen present?
Agglutination or clumping will occur
What does rapid Immunomigration tests use?
Colloidal gold to provide a color change and results
Where are Immunodiffusion tests completed?
Laboratories
What do Immunodiffusion tests require?
Specialized equipment such as an agar plate and electrical current
What is tuberculin skin testing used for?
Gold standard of identification of Myobacterium Boris
causative agent of Bovine Tuberculosis
What indicates a positive tuberculin skin test?
When the bovine site reaction exceeds the avian site reaction by more than 4mm
What is a PCR test used for?
Used to find small amounts of genetic material in a sample
How is a PCR test different than all of the other tests?
Does not require the pathogen to be alive and does not require the patient to have an antibody reaction to the pathogen
How do PCR test work?
Process of amplification
genetic material is copied enough until is can be detected
Do dogs have antibodies or antigens? What does this mean for them?
Dogs have antigens not antibodies present in their plasma.
will not react to own blood
Will not react to the same blood of another animal during a transfusion
After ONE transfusion of another blood type, they will not react
Do cats have antibodies or antigens in their blood? What does this mean?
Cats have antibodies
will react when exposed to another type of blood
Should be typed prior to a transfusion
Have a higher incidence of reaction when given blood that isn’t theirs
How is the “type” of blood determined?
Determined by antigens present on the membrane of the erythrocyte
What is the gold standard for blood transfusions?
All animals should be typed and cross matched prior to a transfusion
Why do some practices not blood type dogs prior to a transfusion?
If the patient is only expected to have one transfusion AND that the animal has no transfusion record
What does DEA stand for?
Dog Erythrocyte Antigen
How many recognized groups of DEA are there?
8
What is the most important antigen for dogs?
DEA 1
can cause the most severe transfusion reactions
DEA 1.1+
The antigen is present on the erythrocyte membrane
40% of dogs can relieve either 1.1+ or 1.1-
DEA 1.1-
Antigen is NOT PRESENT on the erythrocyte membrane
universal donors but can only receive DEA 1.1-
What is the most common blood type in cats?
Type A (90%)
Type A Feline Blood
Cats have anti B antibodies that are low in number
What blood type is more common in purebred felines?
Type B
Type B Feline Blood
Cats have anti A antibodies that are high in number
Type AB Feline Blood
Lack antibodies for A or B antigens
universal recipient
RARE
