The RIDA®UNITY EHEC/EPEC test, performed on the RIDA®UNITY platform, is a multiplex real-time PCR for the direct qualitative detection of DNA for virulence factors of EHEC, STEC, EPEC, and EIEC/Shigella spp. in untreated human stool samples and culture samples from people with signs and symptoms of acute gastroenteritis. The test is intended to support the differential diagnosis of E. coli infections (EHEC, EPEC, STEC, and EIEC/Shigella spp.) in patients with symptoms of gastroenteritis in conjunction with other clinical and laboratory findings.
