A doctor examines a urine sample showing signs of hemoglobinuria.

Definition

Noun: - The presence of hemoglobin in the urine: A medical condition where hemoglobin, the oxygen-carrying protein from red blood cells, is found in the urine. This typically indicates the breakdown of red blood cells (hemolysis) and the subsequent release of hemoglobin into the bloodstream, which is then filtered by the kidneys into the urine.

Usage

• As a medical diagnosis or finding: The term is used primarily in clinical and laboratory contexts to describe a symptom or test result.
  • The patient's dark urine led the doctor to suspect hemoglobinuria.
  • Laboratory tests confirmed the diagnosis of paroxysmal nocturnal hemoglobinuria.

Advanced Usage

• "Paroxysmal nocturnal hemoglobinuria (PNH)": A specific, rare, and serious acquired disorder of the blood characterized by the destruction of red blood cells by the complement system, leading to hemoglobinuria, especially noticeable in the morning urine.
  • Treatment for paroxysmal nocturnal hemoglobinuria has advanced significantly with new therapies.
