25
Rouleaux normal in what species?
Horses
26
Rouleaux vs agglutination
R- stacking rbc | A- clumping in immune mediated dz
27
How can you test if rbc are role six or agglutination?
Saline test- toile six will separate bc no bond
28
Nucleated rbc normal in what species
Birds, amphibians, llama, reptiles.
29
What if NRBC seen in cats or dogs
Anemia
30
Basophillic stippling normal in what species
Cats and cows
31
Howell-jolly body appearance. Seen with what?
Eccentric- one dot not centered. Regenerated anemia
32
The cause of heinz bodies
Tylenol toxicities. NSAID or Iron toxicity..
33
You may see 5% heinz bodies in this species..
Cats
34
Name for reticulocytes if stained with NMB/diff quik
NMB- retic | Diff quik- polychromatophil
35
Immature rbc
Reticulocytes
36
What if lots of retics? None?
Lots- regenerative anemia. None- bad bone marrow
37
Are punctate or aggregate older?
Punctate
38
What species has aggregate reticulocytes?
Cats
39
What species do you centrifuge the PCV twice the time? (6 min)
Goats and sheep
40
Why centrifuge goat and sheep blood twice?
Cells small. 4-5 microns. Takes longer to pack them
41
What determines % of rbc in circulating blood volume
PCV/HCT
42
Purpose of hemoglobin
Carries o2. Gives cell color
43
Assists in acid-base regulation by eliminating co2
Hemoglobin
44
Least accurate rbc indices
MCH
45
RDW stands for
Red cell distribution
46
Reticulocytes are not seen in this species
Horses
47
If reticulocytes are seen in dog or cat...
Regeneration of RBC :)
48
What 3 findings can you see in Buffy coat
Parasites- microfilaria, babesia
49
TP is influenced by what
Hydration status
50
TP measured with
Refractometer and automated chemical analyzer
51
Platelets can be found in clumps esp in
Cats and cows
52
Platelets AKA
Thrombocytes
53
Primary vs secondary hemostasis
Primary- formation of platelet plug And vessel spasm | Secondary- coagulation cascade, ends in fibrin formation
54
A bleeding disorder Is an issue with primary or secondary hemostasis ??
Secondary hemostasis
55
primary hemostatic tests
platelet count- numbers | bleeding time- function
56
PT- extrinsic or intrinsic
extrinsic
57
PTT- extrinsic or intrinsic
intrinsic
58
activated clotting time- intrinsic or extrinsic
intrinsic COMMON
59
PIVKA intrinsic or extrinsic
extrinsic
60
maturation of erythrocyte
Rubriblast, Prorubricyte, rubricyte, metarubricyte, reticulocyte, erythrocyte
61
morphology of cell
myeloblast, promyelocyte, myelocyte, metamyelocyte
62
left shift
band cells- alot is an issue
63
right shift
hypersegmented N- no issue
64
Eosinophils typically mean
parasites
65
basophilic stppling means
anaphylaxis, allergic reactions
66
monocyte has what
vacuoles
67
granulocytes vs agranulocytes
granulocytes- BEN, agranulocytes- LM
68
monocytes are seen with
infection
69
granules in basophils are made up of what
heparin and histamine
