GERD Food Sensitivity Test Kit Using Gender-Stratified IgG Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current food sensitivity tests for Gastroesophageal Reflux Disease (GERD) suffer from high false positive and negative rates, high intra-patient variability, and inter-laboratory variability, lacking a standardized method to identify trigger foods with certainty.
Innovation Solution
A test kit and method using a plurality of distinct food preparations with an average discriminatory p-value of ≤0.07 or ≤0.10, stratified by gender, to determine IgG binding and generate a report based on bodily fluids, reducing false positives and negatives.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If standardized food sensitivity testing is implemented, then measurement precision improves, but device complexity increases
Solution Approach 1:
The test kit is divided into discrete components including individual food allergen preparations, specific antibody reagents, and separate control elements. Each component is optimized independently and assembled into a coordinated testing system, allowing for precise measurement while maintaining manageable complexity through modular design.
Solution Approach 2:
The patent establishes specific parameter thresholds including discriminatory p-value ≤0.07 or ≤0.10, gender-specific percentile rankings (90th or 95th), and standardized signal intensity measurements. These quantified parameters enable objective interpretation of test results, improving measurement precision through defined numerical criteria rather than subjective assessment.
2Reliability
If gender-stratified testing is used, then reliability improves, but device complexity increases
Solution Approach 1:
The testing protocol incorporates gender-specific reference ranges and interpretation criteria tailored to male and female populations. Each gender group has customized percentile thresholds (90th or 95th percentile specific to their gender) and signal intensity benchmarks, ensuring that testing standards are locally optimized for each demographic rather than applying a universal standard.
3Measurement precision
If multiple food preparations are tested, then measurement precision improves, but loss of time increases
Solution Approach 1:
The test kit includes a pre-determined panel of food allergen preparations that have been selected based on statistical analysis (discriminatory p-value ≤0.07 or ≤0.10) to represent the most clinically relevant food triggers. This preliminary selection of high-probability food allergens allows comprehensive testing of multiple food types without requiring exhaustive testing of all possible food items, thus improving identification accuracy while limiting testing duration.

AI summary
Contemplated test kits and methods for food sensitivity are based on rational-based selection of food preparations with established discriminatory p-value. Particularly preferred kits include those with a minimum number of food preparations that have an average discriminatory p-value of ≤0.07 as determined by their raw p-value or an average discriminatory p-value of ≤0.10 as determined by FDR multiplicity adjusted p-value. In further contemplated aspects, compositions and methods for food sensitivity are also stratified by gender to further enhance predictive value.
