nRBC (Nucleated Red Blood Cells)
Nucleated red blood cells are immature erythrocytes still containing their nucleus and are normally present only in bone marrow after infancy. Their presence in adult blood suggests severe marrow stress from hemolysis, hypoxia, blood loss, or marrow infiltration, and has been associated with increased mortality in critically ill patients.
