How is E. coli infection diagnosed?

The diagnosis is made by finding E. coli in a stool culture. If you have bloody diarrhea, see your doctor as soon as possible. Your doctor will do a culture to find out if you have E. coli in your intestines. The culture has to be taken in the first 48 hours after the bloody diarrhea starts.
