What does MCV stand for and what is it
what occurs when it increases and decreases. |
Mean Corpuscular Volume; the avg. volume of a RBC
increase:hyperchromasia, decreases: hypochromasia |
|
MCH? what does it stand for and what does it mean?
|
Mean Corpuscular Hg;it is the avg of hg in aRBC
|
|
MCHC?
|
Mean Coruscular Hg Concentration; it measures the hg in the PCV
|
|
What does a hyperchromic cell look like vs a Hypochromic cell
|
 Picture |
|
What is the difference between polychromasia and reticulocytes?
|
 1= immature RBC stained with Wright-Giemsa stain 2=immature RBC stained with new mythylene blue both are reticulocytes it just depends on the staining that is done |
|
What is the word for these RBCs and what is the WBC in the picture?
|
Anisocytosis(and increase in degree of size variability); Lymphocyte
|
|
Micro vs. macrocytosis? and which measurement can be used to indicate between the two
|
Indicated by MCV and they also indicate the size of the RBC compared to normal sizes
Macrocytic RBCs are larger than normal and Microcytic are smaller |
|
What is Poikilocytosis?
|
 Abnormal RBC shapes |
|
What are the two main differences of a spherocyte and a normal RBC
what is it associated with? |
 They are smaller than normal and the RBC has a darker stain and lacks a cental pallor Ass. with immune mediated destruction of RBC |
|
What are Schistocytes and how do they obtain this shape?
|
 They are RBC fragments; caused by mechanical disruption(when they are squeezed through tiny capillaries |
|
What is the cause towards Target cells/ codocytes?
|
There us too much membrane compared to Hg
|
|
Stomatocyte: what is it ass. with?
|
Liver disease and electrolyte imbanace
|
|
Dacryocytes vs. Elliptocytes
|
D= tear shaped and e=oval shaped (camel cells)
|
 What is this type of inclusion, and what does it represent? why is it common in cats? |
Heinz bodies and it is seen in precipitation of oxidized Hg (basically denatured Hg that is push to the side); because they lack RBC production and have unique hg structure
|
 What is this cell and when can it be found? |
Basophilic strippling and it is found with lead poisoning
|
