Decreased level of WBCs can be evidence of? immunosuppression
Elevated level of MCVs can be evidence of? macrocytic (large) cells, possible anemia
Decreased level of MCVs can be evidence of? microcytic (small) cells, possible iron deficiency anemia
Elevated level of MCHs can be evidence of? macrocytic (large) cells, possible anemia [but measure amt. of Hgb by weight per RBC]
Decreased level of MCHs can be evidence of? microcytic (small) cells, possible iron deficiency anemia [but measure amt. of Hgb by weight per RBC]
