These tests detect the presence of disease-causing (pathogenic) Escherichia coli that produce Shiga toxins. E. coli bacteria commonly occur in nature and they are a necessary component of the digestive process in humans and most other mammals.
In addition to severe diarrhea, Shiga toxin-producing E. coli (STEC) can cause hemolytic uremic syndrome (HUS), a serious illness that may lead to kidney failure and even death if not treated properly. Tests for STEC are used to make an accurate diagnosis and help guide treatment. These tests may also be used to help recognize and track suspected outbreaks of STEC.
