In this study we observed that out of nonanemic children (having Hb > 11.0 g/dl), microcytosis was seen in 107 (22.6%) cases while hypochromia was present in 72 (15.2%) children.
Hypochromia is characterized by MCHC less than 32 g/dl (normal 32-36 g/dl), with RBCs having less color than normal (DeLoughery, 2014).
Although the Hb [A.sub.2] level was significantly elevated, the corresponding hemogram did not demonstrate microcytosis or hypochromia.

Regarding the pancytopenia, a peripheral blood smear showed a moderate normocytic anemia with mild hypochromia; a few ovalocytes, burr cells, and schistocytes; and increased rouleaux formation.
The blood smear has typical thalassemic features, including hypochromia, target cells, basophilic stippling, occasional microcytes, and red cell fragments [10].
