  2. Labs in anemia of chronic disease.
    Hgb most often 8-10.  MCV and MCHC normal, so normocytic and normochromic but may progress to microcytic with time.  Retic count often below normal.  Not producing many new RBCs.
  3. What MCV levels are considered microcytic?
    below 80 fL
  4. What MCV levels are considered macrocytic?
    100+ fL
  5. what does fL stand for in the MCV measurement?
    femtoliters
  6. How is MCV arrived at?
    hematocrit divided by total RBCs multiplied by 10
