Impaired DNA synthesis in hematopoietic cells leads to megaloblastic anemia, so the peripheral smear shows hypersegmented neutrophils as a hallmark. Neutrophils with five or more lobes reflect delayed nuclear maturation caused by folate or vitamin B12 deficiency, while cytoplasmic maturation proceeds, giving a macrocytic picture overall. This combination makes hypersegmented neutrophils the most characteristic smear finding for megaloblastic anemia. Spherocytes point to membrane disorders like hereditary or autoimmune hemolytic anemia, target cells appear in liver disease and certain hemoglobinopathies, and basophilic stippling is typical of lead poisoning and sideroblastic anemia, not classic megaloblastic anemia.
