How is hemolytic-uremic syndrome diagnosed?

Hemolytic-uremic syndrome (HUS) can be diagnosed by blood tests and by testing your urine for blood and protein. During a blood test, blood is drawn so cells may be examined for damage. Testing the blood is also done to check for an increase in the amount of white blood cells (the cells used to fight infection) and a decrease in the red blood cells or platelets (the cells that become damaged).

You may be asked to provide a sample of your urine so they can test it for blood and protein. Blood and protein in the urine both signify a problem with your kidneys.
