Exam 1: RBC/WBC eval Flashcards
1
Q
Normal dog PCV
A
35-50%
2
Q
PCV (Packed Cell Vol)
A
% of whole blood that is erythrocytes aka hematocrit (HCT) (calculated value on CBC)
3
Q
Buffy coat
A
- After spun down, white band above RBC’s
- WBC’s, platelets, nucleated erythrocytes
4
Q
Plasma
A
-After spun down, layer above buffy coat
5
Q
Yellow plasma
A
- Normal or Icteric (due to increased bilirubin concentration from heme breakdown in the blood )
- LA - icteric or carotene pigment due to diet
6
Q
Lipemic plasma (white)
A
- Excess of chylomicrons (lipemia)
- Postprandial collection or lipid metabolism dz
7
Q
Red plasma
A
- Hemolysis causing hgb presence in plasma
- In-vtiro causes (technique, or lipemia presence)
- In-vivo causes (hemolytic anemia)
8
Q
Total Protein
A
- Refractometer estimates protein concentration in plasma
- assumes all other plasma solutes are normal. If abnormal, TP increased falsely
- Measure Albumin & globulin on chem to check
9
Q
Normal TP in dogs
A
6.5 - 8 gm/dl
10
Q
What can artificially increase TP?
A
- increased Albumin, globulin
- urea, glu, cholesterol (negligible effect)
- Lipemia
- severe hemolysis
11
Q
In dehydration, what happens to albumin?
A
increases
likely to see increased TP as well
12
Q
Increased PCV, increased TP indicates what?
A
dehydration
13
Q
Decreased PCV, decreased TP indicates what?
A
blood loss
14
Q
WNL PCV, decreased TP indicates what?
A
decreased prot production or
increased prot loss
15
Q
WNL PCV, increased TP indicates what?
A
increased globulin production
dehydration in an anemic patient
