Low-Cost, Volume-Controlled Dipstick Urinalysis for Home-Testing

Area of Science:

• Biomedical Engineering
• Clinical Chemistry
• Medical Diagnostics

Background:

• Dipstick urinalysis is a common diagnostic tool, but manual performance is prone to errors due to reliance on human factors like color vision and lighting.
• Inconsistent technique and subjective color interpretation can lead to inaccurate physiological condition estimations.
• The need for accurate, accessible, and user-friendly urinalysis methods, especially for home-based testing, is significant.

Purpose of the Study:

• To describe the development of a customizable device for automated dipstick urinalysis.
• To enable accurate, at-home self-testing by eliminating manual error sources.
• To provide a low-cost, easily assembled solution for automated urine analysis.

Main Methods:

• Development of a customizable device to automate key steps of dipstick urinalysis.
• Customization of the device for various dipsticks and integration with a mobile app for result analysis.
• Demonstration of the device's functionality and comparison with the standard dip-and-wipe method.

Main Results:

• Successful creation of a cheap-to-manufacture and simple-to-assemble automated urinalysis device.
• Demonstrated ability to customize the device and associated mobile app for specific dipsticks and analysis.
• The proposed automated method shows potential for robust operation and accurate results compared to manual techniques.

Conclusions:

• Automated dipstick urinalysis using the developed customizable device can eliminate errors associated with manual testing.
• The device offers a viable solution for accurate, accessible, and affordable self-testing of physiological conditions at home.
• Further development and validation can enhance the utility of this automated approach in clinical and personal health monitoring.
