To evaluate the impact of antimicrobial interventions (whether
pharmaceutical or botanical) on the gut microbiome and guide
probiotic or prebiotic recommendations [10].
Digestive Complaints with Malabsorption
Tests like BiomeFX evaluate digestive capacity through markers
such as pancreatic elastase, fat malabsorption, and inflammation,
making them valuable when malabsorption is suspected [11].
Inflammatory Conditions
When inflammation is a predominant feature (inflammatory bowel
disease, microscopic colitis), stool inflammatory markers provide
useful diagnostic information [12].
Key Advantages
● Directly assesses gut microbiome composition and function
● Evaluates digestive capacity and enzyme production
● Identifies potential pathogens and opportunistic organisms
● Provides inflammation metrics to guide intervention [13]
Cyrex Array 22 (Irritable Bowel/SIBO Screen)
Overview and Mechanism
Cyrex Array 22 is a blood test that evaluates immune reactions to
bacterial toxins and intestinal barrier proteins. Unlike other tests
that assess the presence of bacteria or their metabolites, Array 22
measures the host immune response to these components,
providing insight into the immunological aspect of intestinal
dysbiosis [14].
Primary Clinical Applications
Array 22 testing is most valuable in these clinical scenarios:
