Gastroenterology Testing & Diagnosis

Advanced, accurate testing is the first step to diagnose your digestive or GI (gastrointestinal) problem. University Health offers a free, online colorectal cancer risk assessment and has the latest testing procedures to diagnose and treat your condition.

Your doctor will examine you and may order lab tests to determine future testing needs.

Gastroenterology involves a thorough examination of several internal organs and processes. We have specialized equipment allowing our doctors to see these interior structures through minimally invasive procedures with tubes outfitted with lights and cameras.

Diagnostic Testing We Offer

We offer special diagnostic tests, including:

  • Capsule endoscopy
  • Hydrogen breath testing for irritable bowel syndrome (IBS)
  • Small intestine bacterial overgrowth (SIBO)
  • Lactose malabsorption 
  • Motility testing

We also have gastrointestinal experts who perform a wide range of procedures necessary to check for gastrointestinal problems.

Bronchoscopy allows your doctor to see inside your lungs. This test may be necessary if you have an esophagus or lung disorder.
Endoscopic Ultrasound (EUS)

Your doctor passes an endoscope equipped with an ultrasound transducer into your stomach through your mouth. This allows your doctor to see your pancreas, liver, gallbladder, upper intestines and the areas around them. This state-of-the-art technology allows our endoscopy team to detect problems and take tissue samples through the endoscope for examination.

EUS requires extensive experience and skill to help patients get an accurate diagnoses. Our advanced endoscopists have performed hundreds of EUS procedures and are among the most experienced in the region.

Liver Biopsy
Your doctor may want to take tissue samples or a biopsy of your liver if another test has shown a possible liver disease.
