Hematuria indicates blood in the urine, defined by the presence of intact red blood cells in the urine. This can be detected microscopically, and when enough RBCs are present, urine may appear red or pink. A dipstick test can detect occult blood but cannot distinguish whether the blood comes from intact red cells or free hemoglobin/myoglobin; actual RBCs seen under the microscope confirm true hematuria. The other listed findings describe bilirubin in urine (bilirubinuria), protein in urine (proteinuria), and glucose in urine (glucosuria), respectively. Hematuria specifically points to red blood cells in the urine, signaling possible bleeding anywhere in the urinary tract or kidney.
