Determining whether Escherichia coli O157:H7 may be the cause of diarrhea
Reflexive testing for Shiga toxin and/or E coli O157:H7 nucleic acid amplification test-positive feces
This test is generally not useful for patients hospitalized more than 3 days because the yield from specimens from these patients is very low, as is the likelihood of identifying a pathogen that has not been detected previously.
This test provides evidence of the presence of the bacterium, Escherichia coli O157:H7, in feces, in a viable state, and provides an isolate for submission to a health department, if needed. Minnesota healthcare providers are required to report all confirmed or suspected cases of E coli O157:H7 and other Shiga toxin-producing E coli to the Minnesota Department of Health. Mayo Clinic Laboratories clients should refer to their local health departments regarding public health submission of E coli O157:H7 and other Shiga toxin-producing E coli isolates.
