Key Differences
Hematuria is a medical term that describes the condition when blood, specifically red blood cells, is found in the urine. This can occur for various reasons, such as urinary tract infections, kidney diseases, or physical trauma.
Hemoglobinuria, on the other hand, indicates the presence of free hemoglobin in the urine. Hemoglobin is a protein found in red blood cells that carries oxygen. When these cells break down prematurely, hemoglobin is released, and if it passes into the urine, it results in hemoglobinuria.
While both Hematuria and Hemoglobinuria involve the abnormal presence of substances in the urine, they signify different issues. Hematuria indicates blood cells in the urine, which could be visible or microscopic. In contrast, Hemoglobinuria points to the presence of free hemoglobin, suggesting red blood cell hemolysis or breakdown.
It is essential to differentiate between Hematuria and Hemoglobinuria when diagnosing because their underlying causes and subsequent treatments might differ. Hematuria might hint at conditions directly affecting the urinary system, whereas Hemoglobinuria could be a sign of conditions that cause rapid destruction of red blood cells.
In practice, Hematuria might present as pink, red, or cola-colored urine due to the presence of red blood cells. Hemoglobinuria, however, can result in a brown or dark colored urine, stemming from the free hemoglobin and its byproducts.

Compare with Definitions
Hematuria
An indication of possible injury or disease in the urinary system.
Hematuria can sometimes indicate a more serious underlying condition.
Hemoglobinuria
The presence of free hemoglobin in the urine due to red blood cell breakdown.
Hemoglobinuria can be a sign of a serious medical condition and requires prompt attention.
Hematuria
A clinical sign that can be either gross (visible) or microscopic.
Her Hematuria was microscopic, so it wasn't visible to the naked eye.
Hemoglobinuria
Often results in dark or brown-colored urine.
His Hemoglobinuria was evident from the dark hue of his urine.
Hematuria
May present without pain or other symptoms.
Despite having Hematuria, he experienced no discomfort or pain.
Hemoglobinuria
Indicates excessive hemoglobin release that kidneys cannot fully reabsorb.
In cases of severe Hemoglobinuria, the kidneys are overwhelmed by the amount of free hemoglobin.
Hematuria
Can result from infections, stones, or trauma.
The patient's Hematuria was traced back to a recent bladder infection.
Hemoglobinuria
Indicates hemolysis or the premature destruction of red blood cells.
A significant hemolysis event led to her developing Hemoglobinuria.
Hematuria
Hematuria or haematuria is defined as the presence of blood or red blood cells in the urine. It can be classified according to the quantity, the anatomical origin of bleeding and the occurrence during bleeding.
Hemoglobinuria
Can result from certain infections, toxins, or medications.
Malaria, a common cause in certain regions, can lead to Hemoglobinuria.
Hematuria
The presence of blood in the urine.
Hemoglobinuria
Hemoglobinuria is a condition in which the oxygen transport protein hemoglobin is found in abnormally high concentrations in the urine. The condition is caused by excessive intravascular hemolysis, in which large numbers of red blood cells (RBCs) are destroyed, thereby releasing free hemoglobin into the plasma.
Hematuria
(pathology) The presence of blood in the urine
Hemoglobinuria
The presence of hemoglobin in the urine.
Hematuria
Passage of urine mingled with blood; blood in the urine.
Hemoglobinuria
(medicine) The presence of hemoglobin in the urine.
Hematuria
The presence of blood in the urine; often a symptom of urinary tract disease
Hemoglobinuria
Presence of hemoglobin in the urine
