The presence of free hemoglobin in urine, usually indicating damage to red blood cells that allows hemoglobin to leak into the bloodstream and be filtered by kidneys.
From 'hemoglobin' + Greek 'ouron' (urine). Developed as a diagnostic term in the 19th century when physicians could observe and describe abnormal urine contents, indicating serious underlying hemolysis or kidney damage.
Hemoglobinuria turns urine dark red or brown—it's a red flag that red blood cells are being destroyed somewhere in your body, whether from severe burns, transfusion reactions, malaria, or certain medications.
