What to expect from functional abdominal testing

First your doctor will ask questions to create a detailed history of how the pain started, how it progressed, its location and other factors that can often suggest a diagnosis of functional pain. Then, he or she will do a physical exam and check your child’s growth to make sure it’s normal. In functional pain, growth is good and the physical exam is normal.

How do providers at Children’s Colorado make a diagnosis?

After the physical exam, basic blood, urine and stool tests are often performed to screen for other conditions that can cause recurrent pain, like an infection or lactose intolerance. x-rays, other imaging studies, extensive lab tests and endoscopy are only recommended for children whose history, exam or basic lab results don’t fit with the diagnosis of functional pain.
