Microcytic, hypochromic anemia on CBC is characterized by which pattern?

Microcytic hypochromic anemia reflects red blood cells that are smaller than normal and have less hemoglobin, making them paler. On the CBC this appears as a low mean corpuscular volume (MCV) together with a low mean corpuscular hemoglobin (MCH) or a low mean corpuscular hemoglobin concentration (MCHC). This combination is the classic signature of reduced hemoglobin content in small cells, as seen with iron deficiency, sideroblastic anemia, and thalassemias. The other patterns don’t fit because a high MCV indicates larger cells (macrocytosis), normal MCV with normal MCH indicates normocytic normochromic cells, and a high MCV with low MCHC would imply macrocytosis with hypochromia, not the microcytic hypochromic picture described.
