A just-in-time stool logistics network for hospitals and reference labs needing rapid, traceable samples for C. diff, norovirus, and emerging pathogen diagnostics. Lab managers on G2 and Capterra complain that existing couriers and LIS tools are built around blood and tissue, not high-biohazard stool with strict stability windows and exposure rules. InfectioStool builds a verticalized layer that offers: - hospital-friendly ordering integrated into LIS/EMR for infectious stool tests - certified couriers with biohazard-specific SOPs and time/temperature IoT tracking - automated exposure documentation and incident workflows - analytics on turnaround-time, leakage incidents, and wastage. The business charges per-shipment and via annual contracts with health systems, with a compliance and route-density moat that strengthens as more ID labs come on board.
