GI Effects Comprehensive Profile - Stool

The Latest Advancement in Comprehensive Stool Analysis

The GI Effects Comprehensive Profile is unlike any other stool analysis profile, going beyond the standard parameters for identifying gastrointestinal disorders.

Please visit our new website to order the GI Effects Comprehensive Profile.

The GI Effects Comprehensive Profile uses the best of both culture-based and molecular approaches for stool-based gastrointestinal diagnostics. O&P technology can identify an unlimited number of parasites and is the gold standard diagnostic methodology for parasite detection, while PCR technology provides an expansive assessment of anaerobic gut microflora.

Advantages of the GI Effects Stool Profile

  • Enhanced Clinical Utility
    Clinical utility for parasite detection is enhanced with O&P technology, the current clinical diagnostic standard of care. Optimized Parasite Recovery (OPR) is Genova Diagnostics’ version of O&P technology which utilizes a concentration process to optimize parasite detection. Because the vast majority of commensal gut microflora are anaerobes that present culture challenges, microbial DNA analysis is utilized to optimize the assessment of gut microbial composition.
  • 1-Day or 3-Day Sample Collection Option
    Parasite Recovery Literature suggests that >90% of enteric parasitic infections are detected in a sample from a single stool collection. Increased recovery results from the collection of additional specimens on separate days, and given that, scientific bodies such as the Centers for Disease Control recommend a minimum of three samples on three separate days to optimize parasite detection. Parasites have been detected in 20-24% of U.S. patients with mild to moderate GI symptoms.

Why Use Stool Analysis?

Gastrointestinal function is important for general health. The intestinal tract contains significant amounts of bacteria which, when imbalanced, have been associated with IBS and IBD, immune disorders, diabetes, and cardiovascular disease. Balancing gut microflora is key for optimizing digestion and absorption of nutrients, as well as metabolic functions. Poor digestion and malabsorption can lead to immune dysfunction, nutritional insufficiencies, mental/emotional disorders, and autoimmune diseases.

  • Anaerobes
    Anaerobes, making up over 95 percent of microbiota in the gut, can be identified using GI Effects.
  • Parasites
    Using O&P (OPR) technology, an unlimited number of parasites can be detected. To date, over 40 parasitic organisms have been identified.
  • Adiposity Index
    Measures imbalances of the two predominant bacterial groups in the human GI tract, bacteroidetes and firmicutes, which have been associated with obesity in some studies.
  • Absorption
    Indicates absorption issues with elevated levels of long-chain fatty acids, cholesterol, or total fat (the sum of gut lipids).
  • Inflammation
    Lactoferrin is a marker of gut immune function, and is clinically utilized to identify the presence of gastrointestinal inflammation.
  • Sensitivities
    Pharmaceutical and botanical sensitivities are included.
