Engineering Steps for Mobile Point-of-Care Diagnostic Devices

Area of Science:

• Biomedical Engineering
• Medical Diagnostics
• Mobile Health Technology

Background:

• Mobile phones offer advanced capabilities for point-of-care diagnostic development.
• Despite academic progress, few mobile diagnostics have achieved field testing, commercialization, or regulatory approval.

Purpose of the Study:

• To address challenges in mobile diagnostic development and propose strategies for researchers.
• To provide a resource for accelerating the development and approval of new mobile diagnostics.

Main Methods:

• Review of published mobile phone diagnostics and lessons learned.
• Inclusion of recommendations from regulatory and public health agencies (e.g., FDA, WHO).
• Outlining a four-step development process: Needs Assessment, Technology Development, Preclinical Verification, and Clinical Validation.

Main Results:

• Identified common pitfalls in mobile diagnostic development, including misaligned technical parameters with clinical impact and reliance on lab resources.
• Emphasized the need for equipment-free, mobile-agnostic devices and simulating field conditions during laboratory verification.
• Stressed the importance of field testing in conditions matching intended use and focusing on fundamental research principles.

Conclusions:

• The future of mobile point-of-care diagnostics is promising but requires addressing fundamental research and development challenges.
• Adherence to a structured development process with a focus on needs assessment and realistic validation is crucial.
• Implementing the suggested strategies can streamline development, increase productivity, and lead to more approved diagnostics, ultimately reducing global disease burden.
