Quiz 2 Flashcards
Anisocytosis
RBS of unequal sizes
Poikitocytosis
Bizarre shaped RBCs shape altered drastically
Ehinocyte
Equally shaped projections occur on RBCs
Acanthocyte
Protrusions on RBC long and irregular in length
Schizocytes
RBC fragments
Keratocyte
RBCs shaped like a helmet
Leptocyte
RBC has increased membrane to volume ratio
Target cell
A special kind of leptocyte
Spherocyte
May occur in dogs with anemia, more contents than membrane
Stomatocyte
RBC that may occur in a dwarf
Hypochromic
RBC has less Hgb than it should
Polychromatic
RBC is bluish in color
Metarubricyte
Nucleated RBC
Howell-Jolly body
Nuclear remnant
Basophilic stippling
Blue dots seen in RBC on routine stain
Heinz bodies
Clear to pale projections off RBC on routine stain, pale blue in NMB
Retic count
Bone marries response to anemia
Agedor damaged RBCs are removed from the blood primarily by ____ locate in 3 organs:
Macrophages
Spleen
Liver
Bone marrow
Mononuclear phagocytic system
Spleen
Liver
Bone marrow
3 trends of RBC maturation
Cells get smaller
Nucleus disappears
Baso to eosinophilic
Least mature to most mature RBC stages
Rubriblast Prorubricyte Rubricyte Metarubricyte Polychromatic
Abnormal cells are found in the
10X feathered edge
RBC morphology assessment
100X monolayer
Platelet estimate magnification
100X monolayer
How many days it takes to see anemia in peripheral blood
5-7
The retic is equivalent to the ____ cell on the routine stained blood film
Polychromatic
Two kind of retics
Punctate- polka dots- older
Aggregate- clumps- younger
Only retic counted in cats
Aggregate
Stimulus for erythropoiesis is _____ the hormone ____ is produced by the _____ in response to the stimulus
Hypoxia
EPO
Kidneys
3 effects EPO has on bone marrow
Increase Hgb synthesis
Release of PPSC to diff into rubriblast
Release of immature RBCs into the peripheral blood system
Tube for CBC
PTT
Tube for retic count
PTT
Sample used to name stain ratio
1 drop EDTA whole blood
1 drop NMB
Incubation time of NMB
10-20 min
Retic make and examine
Blood film- thin monolayer
Magnification of retic exam
100 X
Counting retics
1000 RBCs & tally retics
Purpose of retic count
To see bone marrows response to anemia
