How is E. coli Infection Diagnosed?
Infection with E. coli O157:H7 or other Shiga toxin-producing E. coli is usually confirmed by the detection of the bacteria in a stool specimen from an infected individual. [1, 54]
Most hospitals labs and physicians know to test for these particular bacteria, especially if the potentially infected person has bloody diarrhea. Still, it remains a good idea to specifically request that a stool specimen be tested for the presence of Shiga toxin-producing E. coli.
