Hemoglobinuria is a condition in which the oxygen transport protein hemoglobin is found in abnormally high concentrations in the urine. [1] 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. [2]

Hematuria can be classified according to visibility, anatomical origin, and timing of blood during urination. [1] [6]In terms of visibility, hematuria can be visible to the naked eye (termed "gross hematuria") and may appear red or brown (sometimes referred to as tea-colored), or it can be microscopic (i.e. not visible but detected with a microscope or laboratory test).
Hematuria (red blood cells in the urine) [11] Proteinuria (protein in the urine) ranging from sub-nephrotic (<3.5 g/day) to >10 g/day, [7] although it is rarely above nephrotic range proteinuria levels. [12] Hypertension [13] resting blood pressure is persistently at or above 130/80 or 140/90 mmHg. [14] Blurred vision [4]
Blood tests (to monitor levels of platelets, red blood cells, and white blood cells), stool tests (especially to check for microscopic or macroscopic levels of fresh or old blood), urinalysis (to help monitor kidney function, like blood urea nitrogen, or BUN, levels, pH, and for blood in the urine- hematuria) [3] Differential diagnosis
Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...
Thus, a positive result for blood can represent the presence of red blood cells , free hemoglobin (hemoglobinuria), or myoglobin (myoglobinuria). [51] Red blood cells can sometimes be distinguished from free hemoglobin or myoglobin as the former causes a speckled pattern on the test pad while the latter results in a uniform color change.
Hereditary pyropoikilocytosis (HPP) is an autosomal recessive form of hemolytic anemia which typically presents at infancy or early childhood, characterized by abnormal red blood cell morphology including "budding red cells, fragmented red cells, spherocytes, elliptocytes, triangular cells, and other bizarre-shaped red cells."
