ROI Calculation Logic

Chorioamnionitis affects ~5% of pregnancies annually, causing preterm birth and neonatal complications. If this technology enables early intervention for 10% of at-risk pregnant individuals, saving an average of ~$6.5K (AI est.) per case (hospitalization, medication, NICU), the potential annual savings for ~300,000 births could be ($6.5K × 300,000 × 5% × 10%) = ~$1M (AI est.). Including QOL improvements and healthcare efficiency, the total impact could reach ~$2M (AI est.) annually.

Speed to Market
6× faster than in-house development
This technology is built upon the established foundation of 16S rRNA gene analysis, with a clearly defined patented prediction algorithm based on specific bacterial groups and their thresholds. This allows licensees to bypass extensive R&D and clinical validation, focusing instead on integration with existing genetic analysis equipment, information systems, and reagent kit development, significantly accelerating time to market. The established prediction logic enables rapid deployment from the demonstration phase.
