The Solution

Syphilis testing in rural communities is inaccessible and expensive. This hypothesis focuses on using microfluidic chips to create an inexpensive and easy to use syphilis testing kit - and suggests a pilot plan in India; partnering with a mobile medical van service to increase usage of the tests.

Microfluidic Chips:

After conducting extensive research, our proposed solution revolves around utilizing paper microfluidic chips embedded with specific reagents to detect Syphilis antibodies in blood samples. This innovative approach offers several advantages in terms of cost-effectiveness and accessibility. By leveraging the power of smartphones and machine learning algorithms, we aim to revolutionize syphilis testing in India.

The paper microfluidic chips, functioning as lab-on-a-chip devices, employ the capillary action of paper to transport fluids through microchannels. These chips are integrated with Syphilis-specific reagents, which react with the antibodies present in the blood sample. Leveraging the principle of immunochromatographic assays, widely used in rapid diagnostic tests, these reagents ensure reliable detection. While optimization and validation for this specific application are necessary, the underlying technology already exists.

Smart-Phone Lense:

To analyze the test results accurately, our solution involves attaching a custom mobile application and a clip-on device to smartphones. The attachment consists of a high-resolution camera and a light source, enabling the capture and analysis of images of the paper microfluidic chip. The mobile application utilizes convolutional neural networks (CNN) to analyze these images and determine the presence of Syphilis antibodies. This approach has been successfully employed in projects such as the Malaria initiative, showcasing its potential effectiveness.

To collect blood samples, a fingerstick method is employed, involving a sterile lancet to obtain a small drop of blood. This minimally invasive technique ensures convenience and ease of use. It is important to note that lancets and microfluidic chips should not be reused, ensuring the highest standards of safety and hygiene.

Costs:

In terms of cost, our solution offers a promising alternative to existing diagnostic methods. Paper microfluidic chips can be produced at a lower cost compared to traditional diagnostic tools. The estimated cost per test, including the microfluidic chip, lancet, and smartphone attachment, ranges from $1.05 to $1.55. These figures are subject to variation based on production scale, design complexity, and market conditions. The initial investment in the smartphone attachment can be spread across multiple tests, reducing the per-test cost over time.

Possible Problems + Mitigation:

1. Variations in smartphone cameras: Different smartphones may have varying camera qualities, which could impact the accuracy of image analysis. To mitigate this, we will develop the mobile application to account for variations in camera capabilities and ensure compatibility across a wide range of devices. Rigorous testing and calibration will be conducted to maintain consistent and reliable results.

   
   

2. Stigma associated with smartphone attachments: Some individuals may feel uncomfortable or stigmatized by the use of a camera attachment for testing. To address this, we will implement a comprehensive awareness campaign to educate communities about the benefits and efficacy of our solution. Collaborating with local healthcare workers and community leaders will help establish trust and overcome potential resistance.

   
   

3. Training and capacity building: The successful implementation of our solution relies on the proper training of healthcare workers in rural areas. To address this, we will develop comprehensive training materials and conduct workshops to ensure that healthcare professionals are proficient in using the testing kit. Ongoing support and refresher training will be provided to address any challenges or questions that may arise during the deployment.

   
   

4. Manufacturing scalability: As our solution gains traction, scaling up the production of paper microfluidic chips and smartphone attachments will be crucial. To meet the increasing demand, we will establish partnerships with manufacturers who have the capacity to produce these components at scale. Regular quality control checks and optimization of manufacturing processes will be implemented to maintain consistent quality and affordability.
