What's the most cost-effective way to expand decentralized testing using a handheld immunoassay reader?

The most cost-effective way to expand decentralized testing with a handheld immunoassay reader is usually to standardize a low-cost, high-volume workflow around one platform and push the testing as close to the point of need as possible.

Best practical approach

1. Use the reader for multiple assays

   • Pick a handheld reader that supports several test types, so you’re not buying separate devices for each analyte.
   • This spreads device cost across many tests and improves utilization.

2. Deploy in high-throughput decentralized sites

   • Prioritize clinics, pharmacies, urgent care, community health centers, mobile units, and workplace screening sites.
   • These locations give the best cost per test because they already see patient volume.

3. Choose cartridges/tests with low total cost per reportable result

   • The cheapest reader is not always the cheapest system.
   • Include cartridge cost, calibration needs, maintenance, controls, waste, and staff time.

4. Train non-lab staff with a simple workflow

   • A handheld system is most economical when it can be operated by nurses, med techs, or community health workers with minimal training.
   • Simple SOPs reduce errors and retesting costs.

5. Use connectivity and centralized oversight

   • Connect devices to a cloud or LIS/EHR if possible.
   • Remote QC, automated result capture, and inventory tracking reduce labor and compliance costs.

6. Adopt a hub-and-spoke model

   • Keep the reader at decentralized sites, but centralize procurement, QC monitoring, training, and data review.
   • This avoids duplicating support infrastructure at every site.

7. Start with high-impact use cases

   • Focus first on tests that reduce downstream costs the most, such as infectious disease screening, pregnancy testing, cardiac markers in triage, or chronic disease monitoring.
   • The ROI is strongest where rapid results change immediate decisions.

Rule of thumb

The most cost-effective expansion strategy is: one versatile handheld platform + high-volume decentralized sites + low-cost consumables + centralized digital support.
