Urine Analysis System Creatinine Correction Across Measurement Means
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional urine tests struggle to accurately correct measured quantities of urinary material ingredients using creatinine, as they only account for fluctuations within the same measurement means and methods, failing to account for variations in urine collection conditions.
Innovation Solution
An analysis system that acquires creatinine measurement data and material ingredient data from different measurement means, using the creatinine data to correct the material ingredient measurements, thereby compensating for fluctuations caused by urine collection conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If creatinine correction is performed using only the same measurement means as creatinine, then the correction is simple to implement, but the correction is insufficient for material ingredients measured by different means
Solution Approach 1:
The system integrates multiple measurement means (test strip method and automated analysis method) into a single correction framework. The creatinine measurement data from different measurement methods are both utilized to correct material ingredient concentrations, making the correction system universal across different measurement platforms and improving overall correction accuracy.
2Reliability
If creatinine correction is applied only to urinary elements measured by the same means, then the correction process is simple, but it fails to account for variations in urine collection conditions affecting different measurement methods
Solution Approach 1:
Creatinine measurement data serves as an intermediary reference to bridge and harmonize corrections across different measurement means. By using creatinine from both test strip and automated analysis methods as reference points, the system reliably corrects material ingredient concentrations while accounting for variations introduced by different urine collection conditions and measurement methodologies.
3Loss of information
If only single-method creatinine correction is used, then the data processing is straightforward, but comprehensive information on urinary material ingredients cannot be obtained
Solution Approach 1:
The system merges creatinine measurement data from test strip method and automated analysis method, combining them with material ingredient measurement data to perform comprehensive corrections. This integration of multiple data sources prevents information loss and enables acquisition of more complete and reliable information on urinary material ingredients.

AI summary
An analysis system includes: a creatinine information acquiring section to input creatinine measurement data that indicate a measurement quantity of creatinine in a urine sample; a material ingredient information acquiring section to input material ingredient data that indicate a measured quantity of a material ingredient in the urine sample; and a correcting section to correct the measured quantity of the material ingredient indicated as the material ingredient data, by use of the measured quantity of creatinine indicated as the creatinine measurement data.
