nRBC Flashcards
Where can all stages of nRBCs be found?
in the bone marrow
which nRBCs can occasionally be found in peripheral blood?
- metarubricytes
- rubricytes
what might normally be seen with regenerative anemia?
increased nRBCs
when is anemia considered regenerative?
if reticulocytes are present
to confirm adequate bone marrow response in anemic animals what should be counted? (2)
- reticulocytes
- nRBCs
want the ratio to be greater than 1
what does nRBCs outnumbering reticulocytes indicate?
an inappropriate response
nRBCs commonly outnumber them due to bone marrow damage
increase number of nRBCs may be an appropriate response to what?
increased erythropoiesis due to regenerative anemia
What can cause bone marrow damage? (6)
- necrosis
- inflammation
- endotoxemia
- hypoxia
- myelodysplasia
- neoplasia
causes of inappropriately increased nRBC (5)
- lead poisoning
- extramedullary cell production
- altered splenic function (splenectomy)
- corticosteroids
- trauma

what species are nRBCs rarely seen in? (4)
horses
cows
goats
sheep
adjust WBC count if nRBC count is
5 or more
what effect may nRBCs have on an analyzer WBC count
will increase the WBC count falsely
when do you correct the WBC count?
if nRBCs are greater than or equal to 5
