A smear finding would indicate regenerative anemia?

Explanation:
Regenerative anemia shows the bone marrow actively making new red blood cells to replace those lost. On a blood smear, that activity shows up as reticulocytosis—the presence of more reticulocytes, which are immature red blood cells still containing RNA and staining differently from mature cells. Their appearance in circulation indicates the marrow is responding to the anemia. Microcytosis and hypochromasia reflect problems in hemoglobin synthesis or iron availability rather than a regenerative response, while spherocytes indicate membrane abnormalities or immune-mediated hemolysis. Thus, the smear finding that signals regeneration is reticulocytosis.
