Blood detected in the urine
The best method to diagnose hemolytic uremic syndrome, which can be difficult, is to test the urine for blood. Many times, physicians are able to diagnose hemolytic uremic syndrome based solely on the presence of blood cells in the urine. The earliest symptom of HUS is hematuria (blood in the urine). If you have hematuria, you must see your doctor immediately. The sooner HUS is treated, the simpler it is to manage its symptoms.
