Pillar

Detect

Under Defend, diagnostics serve as a rapid-response countermeasure — surging pathogen-specific tests at pandemic scale to guide treatment, containment, and countermeasure deployment.

Current Status of the Field

Technology

Sequencing-based, host-response, lateral-flow, and isothermal diagnostic approaches are advancing, but point-of-care pathogen-agnostic diagnostics remain far from routine deployment.

Policy

Emergency authorization pathways exist in principle, but they have not been exercised for truly novel pathogen-agnostic tools at the required speed.

Bottleneck

The bottleneck is turning promising platforms into authorized, manufacturable, deployable tests before a crisis rather than after demand spikes.

The Problem

If a novel pathogen emerged tomorrow, we could not test for it at scale for weeks or months. Point-of-care pathogen-agnostic diagnostics do not exist at scale. Current diagnostic development pipelines are too slow, emergency authorization pathways have never been tested at the speed required, and surge manufacturing capacity for tests is insufficient for rapid global deployment. During COVID-19, testing shortages lasted months — against a faster-moving engineered pathogen, that delay could be catastrophic.

The Solution

Sequencing-based diagnostics, host-based assays, lateral-flow tests, isothermal amplification platforms (e.g., LAMP), and pathogen-agnostic platforms are maturing rapidly. The urgent priority is to fund development of these platforms, pre-position regulatory pathways, and build surge manufacturing agreements so that diagnostic capability exists before a crisis — not months into one. Diagnostics bridge detection and response: they confirm what surveillance flags and guide the countermeasures that follow.

Objectives

  • Pathogen-agnostic diagnostics authorized and deployable at the start of any bioincident, with the ability to surge pathogen-specific tests within weeks
  • Point-of-care diagnostics capable of identifying novel pathogens exist at scale, not just in reference laboratories
  • Rapid diagnostic scale-up plans are pre-positioned for pandemics of varying intensity
  • Emergency authorization pathways for novel diagnostics are established and tested
  • Sequencing-based, host-based, lateral-flow, and isothermal amplification (e.g., LAMP) diagnostic platforms are developed and maintained in readiness
