Study population will include patients of any age presenting to the emergency department with abdominal pain and a clinical suspicion of appendicitis. Patients will initially be seen by a treating attending physician or resident. If there is a concern for appendicitis the treating physician will contact one of the ultrasound credentialed EP sonographers to perform a point of care ultrasound. Of note, this is the current standard practice in the ED. By choosing to participate in the study, the patient's treatment is not altered in any way from the current standard practice, but simply is agreeing to allow us to collect data and contact them by phone at the two week follow up. The study sonographer will obtain consent. Parental consent will be obtained for patients under the age of 18.
