Discover How Our Gastrointestinal Testing Supports Clinical Practice

As the world leader in the diagnosis and treatment of gastrointestinal conditions for the last 28 years, we know the importance of laboratory testing in a patient's care. Our disease-specific tests are clinically reinforced, cost-effective, and patient care-driven.

In addition to the latest testing, when you partner with us, you extend your network to include some of the world's leading gastroenterology experts. Our clinicians, laboratorians, and genetic counselors are available for consultation seven days a week to provide interpretive expertise and support.

Early-Onset IBD: Genetic Testing and Its Clinical Application

Patients with diverse spectrums of rare genetic disorders can present with inflammatory bowel disease (IBD). These patients often develop symptoms during infancy or early childhood, along with endoscopic and histological features of Crohn's disease, ulcerative colitis, or unclassified forms of IBD. Our IBD primary immunodeficiency panel identifies variants within genes known to be associated with IBD and immunodeficiency that can help establish a diagnosis and, in some cases, allow for appropriate management and surveillance for disease features based on the gene involved.



  • Providing a comprehensive genetic evaluation for patients with a personal or family history suggestive of IBD, enteropathy, hepatic primary immunodeficiency (PID), or intestinal manifestation associated with immunodeficiency.
  • Establishing a diagnosis and, in some cases, allowing for appropriate management and surveillance for disease features based on the gene involved.
  • Identifying variants within genes known to be associated with IBD, enteropathy, hepatic PID, or related disorders allowing for predictive testing of at-risk family members.

Gastrointestinal Pathogens: Multiplex Panel to Detect 22 Bacterial, Viral, and Parasitic

Our gastrointestinal pathogen panel is a multiplex polymerase chain reaction (PCR) test capable of rapidly and quantitatively detecting DNA or RNA of 22 pathogens (13 bacteria, 5 viruses, and 4 parasites).


  • Rapid Detection—Test results are available the same day that specimens are received. This is consistent 24 hours a day, 7 days a week.
  • Comprehensive and Consolidative—Detection of 22 bacterial, viral, and parasitic pathogens in a single orderable eliminates the need for culture, antigen testing, microscopy, or individual nucleic acid amplification tests.
  • Cost-Effective—In situations where multiple tests would otherwise be performed, this test often provides a more cost-effective option.

Celiac Disease: A Challenging Diagnosis

Working closely with our clinical GI colleagues, we established several cascading algorithms to aid in the diagnosis of celiac disease. These algorithms, each with a specific utility, use automatic reflexing to perform the necessary tests and are available as orderable clinical tests. 

Cascades ensure that testing effectively proceeds in an algorithmic fashion. We recommend a celiac disease serology cascade for most patient situations; however, additional algorithms—comprised of our comprehensive and gluten-free cascades—are available.
