Low-power, low-cost urinalysis system with integrated dipstick evaluation and microscopic analysis

Area of Science:

• Biomedical Engineering
• Clinical Diagnostics
• Microscopy

Background:

• Urine analysis is crucial for diagnosing various medical conditions.
• Current methods can be time-consuming and require specialized equipment.
• There is a need for accessible, integrated point-of-care diagnostic tools.

Purpose of the Study:

• To develop and validate a novel, low-cost device for simultaneous urine dipstick analysis and microscopic examination.
• To assess the accuracy and clinical utility of the integrated device compared to standard protocols.

Main Methods:

• A cellphone-based microscope with oblique illumination was coupled with a urine dipstick reader.
• A power-free filtration system was integrated for accurate particle quantification.
• A custom-built application was developed for data acquisition and analysis.

Main Results:

• The device accurately assessed urine dipstick results and visualized microscopic urine constituents.
• Quantification of particles was achieved with high precision using the integrated filtration system.
• Results demonstrated strong consistency with standard clinical urine analysis protocols.

Conclusions:

• The coupled dipstick and microscopy device offers a promising, cost-effective solution for comprehensive urine analysis.
• The system's ease of use, low power requirements, and accuracy suggest significant potential for clinical applications, particularly in resource-limited settings.
