Finding a Diagnosis
Upon referral to our program, you and your child will meet with our gastroenterologist, psychologist and dietitian so that they may discuss your child’s medical history and perform a physical evaluation. Many of our patients who are referred to the program have undergone some diagnostic tests with their pediatrician or previous gastroenterologist.
Your CHOC gastroenterologist will look at the results of these tests, and may order additional tests to rule out gastrointestinal disorders and conditions. Tests that may be used include:
- Blood tests. Blood tests are done to evaluate whether your child is anemic, has an infection, or has an illness caused by inflammation or irritation. Learn more about blood tests at CHOC.
- Urine analysis and culture. These are done to help assess for urinary tract infections.
- Stool sample. A stool sample is taken to check for the presence of microscopic blood in the stools. Your child’s doctor may also check for the presence of inflammation with stool calprotectin and to check for GI infections. Learn more about stool tests.
- Lactose breath hydrogen test. This test is done to determine if your child is intolerant to lactose, a sugar present in milk and milk products. Learn more about lactose breath hydrogen tests.
- Abdominal X-ray. A simple study that will give the health care provider an idea of how the internal organs look. Learn more about X-rays at CHOC.
- Abdominal ultrasound. A diagnostic imaging technique that creates images from the rebound of high frequency sound waves in the internal organs. Learn more about ultrasounds at CHOC.
- Endoscopy. A test that uses a small, flexible tube with a light and a camera lens at the end (endoscope) to examine the inside of part of the digestive tract. Tissue samples from inside the digestive tract may also be taken for examination and testing. Learn more about endoscopy.
- Colonoscopy. A test that uses a long, flexible tube with a light and camera lens at the end (colonoscope) to examine inside the large intestine. Learn more about colonoscopy.
