Gastroenteritis is often self-limiting, and the care is supportive designed to control symptoms and prevent dehydration. Tests may not be needed. The health care professional often may make the diagnosis based on history of symptoms and physical examination.
If the symptoms persist for a prolonged period of time blood and stool tests may be appropriate to determine the cause of the vomiting and diarrhea.
