Overview
Laboratory Findings
- Lab findings of E. coli enteritis are usually related to the degree of dehydration. Lab findings include:
- WBC count may be normal or elevated
- Elevated concentration of inflammatory markers (e.g. CRP or ESR)
- Chloride-sensitive metabolic alkalosis and electrolyte derangement (commonly hypokalemia)
- Relative polycythemia in cases of dehydration or hemolytic anemia in cases of hemolytic uremic syndrome
- Elevated concentration of BUN
- Elevated creatinine is suggestive of pre-renal acute kidney injury in severe dehydration or onset of hemolytic uremic syndrome

Diagnostic Laboratory Findings
- Stool cultures
- Usually considered reliable diagnostic test
- Diagnosis of E. coli O157:H7 usually requires sorbitol-MacConkey agar
- Serotyping
- ELISA detects Shiga-like toxins 1 and 2 in stools
- ELISA may detect anti-LPS IgM antibodies against some E. coli strains
- Polymerase chain reaction (PCR)
- Detection of E. coli pathogens and Shiga-like toxin
