The anemia is usually mild (Hct = 30-40%), but may be
lower. The RBCs of ACD are usually normochromic/normocytic,
but, especially in time, may be mildly
hypochromic/microcytic (mild decrease MCV and decrease
MCHC).
Typically ACD is associated with low serum iron, normal
or low transferrin, low transferrin saturation, and high
serum ferritin. Bone marrow iron stores are usually
increased.
Ferritin (an acute phase reactant) may be elevated in
inflammation. Low-normal levels of ferritin in a patient
with acute inflammation may be consistent with Fe
deficiency.
