What can we see represented with NMB stained Immature RBC's that is not represented with Diff Quick Stain?
|
Organelles and Ribosomes
|
|
|
What does the presence of aggregate reticulocytes in a cat represent?
|
Active regeneration
|
|
|
What is the required number of fields to be counted for reticulocytes?
|
10 representing (100 RBC's per field)
|
|
|
Provide the formula for the "corrected" reticulocyte count.
|
Patient PCV divided by normal PCV (canine or feline) multiplied by the total "observed" retic count
|
|
|
What would an absolute count of 100,000/ul represent?
|
Regenerative anemia
|
|
|
What is another name for reticulocyte?
|
Immature Erythrocyte
|
|
|
What information are we able to determine from a retic count?
|
The response of the bone marrow to anemia. It can tell us if it is regenerative or non-regenerative.
|
|
|
What is the definition of reticulocyte count?
|
Number of retic counted in a count of RBC's expressed as a percentage.
|
|
|
If we have an observed retic count of 27 with a (canine) PCV of 38, what would our calculation be for the corrected count?
|
Observed =27/1000 = 0.027
0.027 X 100=2.7% Corrected = 27 X 38 /45(Normal Canine PCV) = 2.28% |
|
|
Absolute retic of 120,480; regenerative or non-regenerative
|
Regenerative
|
|
|
True or False, Horses do not have reticulocytes in peripheral blood?
|
True
|
|
|
How do you prepare a slide for the reticulocyte count?
|
By mixing equal part's NMB/Blood. Tap gently on bottom of tube to mix before setting aside to incubate for 15 minutes. Once time is up, prepare a push smear, let dry and read on O/I.
