Diagnosis

To confirm a diagnosis of HUS, your doctor is likely to recommend lab tests, including:

  • Blood tests. These tests can determine if your red blood cells are damaged. Blood tests can also reveal a low platelet count, low red blood cell count or a higher than normal level of creatinine, a waste product normally removed by your kidneys.
  • Urine test. This test can detect abnormal levels of protein, blood and signs of infection in your urine.
  • Stool sample. This test might detect toxin-producing E. coli and other bacteria that can cause HUS.
