Buccal CRP RNA Detection for Noninvasive Inflammation Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for detecting inflammation, such as measuring C-reactive protein (CRP) levels, are invasive and inconvenient, requiring blood draws, which can be intimidating and impractical for patients and healthcare providers.
Innovation Solution
The method involves detecting C-reactive protein (CRP) ribonucleic acid (RNA) as a biomarker from samples obtained from the buccal cavity, such as saliva or sputum, using a lateral flow assay to predict inflammation levels and responsiveness to treatment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional blood tests are used to measure inflammation biomarkers, then measurement precision is improved, but ease of operation deteriorates due to invasive blood draws
Solution Approach 1:
The patent uses buccal cavity epithelial cells as an intermediary medium to detect CRP RNA, replacing the direct blood draw approach. The buccal cells serve as a mediator that contains inflammatory biomarkers and can be collected non-invasively, thus maintaining measurement precision while improving ease of operation.
Solution Approach 2:
The patent detects CRP RNA in buccal cells as a copy or surrogate marker of systemic inflammation rather than directly measuring CRP protein in blood. This copying approach allows inference of inflammation levels from a non-invasive sample, resolving the contradiction between precision and ease of operation.
2Measurement precision
If blood samples are collected for inflammation testing, then measurement precision is improved, but loss of time increases due to required laboratory visits
Solution Approach 1:
The patent enables self-service sampling by allowing patients to collect buccal cell samples themselves without requiring healthcare provider intervention. This eliminates the time loss associated with scheduled blood draws and laboratory visits while maintaining detection accuracy.
Solution Approach 2:
The patent performs preliminary sample collection in the buccal cavity, which can be done at any time without requiring a scheduled laboratory visit. This preliminary action approach allows patients to collect samples conveniently and have them processed later, eliminating time loss from coordinated blood draw schedules.
3Measurement precision
If blood draws are performed for inflammation testing, then measurement precision is improved, but object-affected harmful factors increase due to patient discomfort and stress
Solution Approach 1:
The patent converts the potentially harmful invasive blood draw procedure into a beneficial non-invasive buccal sampling method. By detecting CRP RNA in buccal cells, the system maintains measurement precision while eliminating the harm and discomfort associated with blood draws, turning a harmful procedure into a safe and convenient alternative.
