03 - classification of anemia Flashcards
1
Q
(microcytic)
- microcytic anemia often caused by what?
A
- iron def, sometimes OSS
2
Q
macrocytic anemia indicates what?
A
that marrow is releasing immature cells
3
Q
- hypochromic anemias are what?
- hyperchromic anemias occur when?
A
- RBCs contain less hemoglobin than normal (dec MCHC)
- NEVER!
4
Q
(regenerative anemia)
- seen how many days after blood loss/destruciton?
- what species don’t release reticulocytes into circ?
A
- 2-4 days
- horses
5
Q
(regenerative anemia - acute blood loss)
- typically see what?
- see what with hemangiosarcoma?
A
- reticulocytosis, polychromasia, and thrombocytopenia
- acanthocytes and schistocytes
6
Q
(regen anemia - chronic blood loss)
- results in what?
- normally see what?
A
- iron def anemia
- dec MCV (microcytosis), increased RDW, MCHC usually normal
(keratocytes and schistocytes are common)
7
Q
(regen anemia - destruction)
- IMHA - see what?
A
- spherocytes
8
Q
parasites…
plus cytauxzoon felis (cats). signet-ring shaped inclusions

Q
(nonregen anemia)
- most are micro or normocytic?
2-4. what are three causes?
A
- normocytic
- aplastic anemia (infectious agents, toxins, drugs, or estrogen)
pure red cell aplasia (decreased erythroid precursors in bone marrow)
red cell hypoplasia (infalm disease, chronic renal fialure, endocrine dz, nutritional dz)
