lab 1: RBC morphology Flashcards
avg. canine RBC lifespan
120 days
avg. canine RBC size
7 microns
are normal canine RBC’S large or small
large
a healthy non-anemic dog has less than 1.5% of?
reticulocytes
what is a Howell-jolly body
left over piece of nucleolus
feline RBC’S are _____&____ compared to canine
smaller and more variable in size and shape
what % of feline blood is reticulocytes
1%
what is the look of an equine RBC
small with minimal central palor
what is the look of a bovine (cow) RBC
variation in size with a less distinct central pallor
what is the look of an ovine (sheep) RBC
small with variations to size and shape
what is the look of a caprine (goat) RBC
extremely small with a minimal central pallor
what is the look of a llama RBC
oval with no central pallor
what is the look of a parrot RBC
oval and nucleated
what is agglutination
bridging and clumping
when is agglutination seen
in animals with immune-mediated disorders where an antibody coats the RBC
what is rouleaux
stacked RBC’S
when is rouleaux seen
increased fibrinogen or globulin concentration
when is rouleaux normal
in healthy horses
when is rouleaux seen
in a present inflammatory disease
how do you tell if its rouleaux or agglutination
saline test: add drop of saline to drop of blood. rouleaux will disperse, agglutination will not
what are poikilocytes
RBC’S with abnormal shapes for the species
what is an IMHA
immune-mediated hemolytic anemia
what does IMHA do
animals body is destroying its own RBC’S
AKA: cranation
echinocytes
what is a blister cell
a ruptured form of a keratocyte
AKA: pencil cell or eliptocyte
ovalocyte
AKA: target cell
codocyte
AKA: bar cell
knizocyte
where are Howell-jolly bodies found
in any morphology
