Uh-Oh Labs

The Challenge

Uh-Oh Labs has been in the personalized diagnostic testing market for many years. Their diagnostic tests use the Loop-de-LoopTM platform, enabling simplicity, speed, and lower costs while providing accurate, lab-grade results. In 2021, Uh-Oh Labs was awarded a contract from the National Institutes of Health RDAx Initiative to commercialize its test. Their mobile app, which connected to their proprietary testing instrument via Bluetooth, was in a proof-of-concept stage and needed a complete overhaul to improve workflow and usability for both point-of-care and home environments.

The Outcome

Uh-Oh Labs Dx Pro and Dx Home are apps for iOS that allow individuals to run quick and accurate diagnostic tests, whether in a healthcare setting or at home. This platform helps keep communities safe. The apps received EUA approval in early 2022. It connects with the UOL Instrument using Bluetooth and allows one or more tests to be performed simultaneously. Results are delivered to the Dx app within 40 minutes with clear and specific information. The UOL Instrument is low-cost, and the app is free. The Dx Pro system is a good option for companies, schools, institutions, and clinics to offer quick and reliable diagnostic testing, while the Dx Home app supports users in home environments.

Clear instructions walk the user through collecting samples for the diagnostic test.

Step-by-step instructions with illustrations are provided for the testing process.

Ongoing checklists ensure that testing steps and followed in the correct order.

QR codes make connecting the instrument to the app simple.

Test results are easy to read and list past result history.

Our Approach

Uh-Oh Labs engaged Flower Press Interactive to review the user experience on an existing application and improve usability before launch. The original application was built as a proof of concept and required updating to offer a high-quality user experience. Uh-Oh Labs wished to rebuild the app in Swift to provide high-performance connectivity with the UOL Instrument. We started with stakeholder interviews and reviewed user testing videos to learn about pain points in the current app workflow. We quickly learned that there were points of confusion around how to set up the test correctly. We simplified the workflow and introduced illustrations to make each step clearer. We used Apple’s Human Interface Guidelines to ensure that all app parts were well-structured and intuitive. Once wireframes were approved, we moved on to visual design. We used a pre-existing character as the primary brand element and built a color palette. We created visual designs using clean, lightweight fonts and interface elements.

We built out UI files in Swift and collaborated with a third-party developer to build the app following the visual design. Our team worked on QA and usability testing to ensure that everything was implemented according to plan. Throughout the build process, additional features were identified as necessary. We worked with the client and the third-party developer to make UX recommendations to ensure that all components were designed well and thoroughly considered. Following the build, we collaborated with Uh-Oh Labs to launch related marketing materials, including a marketing website.

Ongoing Growth

Uh-Oh Labs Dx apps are available in the App Store. Test kits, instruments, and related materials are available on www.uhohlabs.com. The company is continuing to expand its offerings into new categories in the diagnostic testing market. We expect to continue seeing great strides in the world of diagnostic healthcare from Uh-Oh Labs.
