Midstream: Platform Development and Assay Formulation This is the core of the industry, where hardware (instruments) and chemistry (assays) are integrated. Value is created through the development of proprietary "closed systems" where specific reagents only work on specific machines, ensuring long-term customer lock-in. Engineering focus is on increasing "walk-away time" for lab technicians and improving the sensitivity and specificity of the tests to reduce false results.

Downstream: Clinical Distribution and Healthcare Integration Diagnostic products are distributed via direct sales or specialized healthcare distributors. At this stage, value is tied to regulatory approvals (such as CE-IVD or FDA clearance) and inclusion in clinical practice guidelines. For hospitals, the value is in "diagnostic stewardship"—the ability to use test results to make immediate decisions regarding isolation, treatment, and antimicrobial use.

End-User and Patient Management The value chain concludes with the clinician and the patient. In a modern healthcare setting, the diagnostic result is integrated into the Electronic Health Record (EHR), allowing for population-level data analysis and better management of public health resources during seasonal surges.
