Tests and diagnosis

By Mayo Clinic Staff

If your doctor suspects hemolytic uremic syndrome, various lab tests may be done to confirm the diagnosis.

  • Blood tests. Blood tests may reveal a low platelet count, low red blood cell count or a higher than normal level of creatinine — a breakdown product of creatine, an important part of muscle — in your blood. A blood sample can also be used to determine if your red blood cells are damaged.
  • Urine test. Your doctor may also collect a urine sample to test for blood in your urine.
  • Stool sample. Additionally, your doctor may take a stool sample to test for the presence of bacteria.
