An improved pediatric patient journey    

Advanced diagnostics for complex conditions

Our unique tests, methodologies, and pediatric reference ranges provide accurate and fast results for complex pediatric gastroenterology conditions. Whether screening patients or monitoring therapeutic management, we cover the full spectrum of gastroenterology testing. We offer a robust menu of genetic tests to identify inherited disorders and provide insights about genetic variations associated with disease presence. Plus, our world-renowned Mayo Clinic gastroenterologists and genetic counselors can help you order tests and consult on the results.

We test for:


Biologics management


Inflammatory bowel disease



Celiac disease


Malabsorption disorders



Helicobacter pylori


Thiopurine management


Minimize disparities

Unique to our lab, we offer the innovative TPNUQ test for thiopurine management. This test provides awareness of a patient's response to medications through genetic testing. We give insight to care teams by using census data and test analytics to assess potential risks in their patient population, helping to minimize disparities and improve pediatric diagnostic care.

Methodologies that make a big difference

We believe in methodologies that go far beyond the standard reference lab approach to pediatric testing. This includes sophisticated reflex testing that helps you determine if there's a clinical need for additional testing — while helping to reduce any unnecessary testing. Our methodologies also include rigorous spot checks to ensure accuracy and greater test sensitivity.


A test that changed a little boy's life

Due to complex symptoms, 8-year-old Hussein was misdiagnosed with IBD his entire life. But a test developed at Mayo Clinic Laboratories changed everything for Hussein and his family. Learn how this specific test could potentially change everything for one of your pediatric patients, too.
