Tests and diagnosis

By Mayo Clinic staff

Your doctor will likely diagnose gastroenteritis based on symptoms, a physical exam and sometimes on the presence of similar cases in your community. A rapid stool test can detect rotavirus or norovirus, but there are no quick tests for other viruses that cause gastroenteritis. In some cases your doctor may have you submit a stool sample to rule out a possible bacterial or parasitic infection.
