ROI Calculation Logic

Early diagnosis of bacterial infections and cancer could significantly reduce late-stage treatment costs. For example, if early detection helps 1,000 patients annually avoid advanced-stage treatment, saving an average of $800 (AI est.) per person in medical expenses (tests, treatments), this could result in an annual economic impact of ~$800K (1,000 patients × $800) (AI est.). This directly improves patient quality of life.

Speed to Market
4× faster than in-house development
The fundamental research for this technology has been completed by Kanazawa University, establishing the principles linking amino acid transport characteristics to cell classification and disease diagnosis. This significantly shortens development time compared to starting R&D from scratch. By combining with existing general-purpose measurement instruments like biochemical analyzers or mass spectrometers, early market entry is possible with minimal development resources.
