Erythrocytes.nucleated

Nucleated red blood cells (nRBCs) are immature RBCs that normally exit the bone marrow and mature before circulating in your blood. The presence of nucleated RBCs in peripheral blood is abnormal and suggests bone marrow stress or disease. This can indicate severe anemia, leukemia, infection, hemolysis, or other serious conditions. Finding nucleated RBCs on a blood smear typically warrants further investigation to identify the underlying cause.
