Rebuilding preventive healthcare through innovation with Diagnostyka 2.0

Diagnostyka is Poland’s largest medical company and a national leader in laboratory diagnostics. With over 150 laboratories and 1,150 collection points, the company conducts more than 160 million tests annually. Driven by the mission to help people take care of their health and live longer, Diagnostyka wanted to strengthen its commitment to preventive healthcare through digital innovation.

After successfully delivering the MVP version of the Diagnostyka app, Miquido joined forces once again with Diagnostyka’s team to elevate the product to the next level, enhancing it both functionally and visually. The new version goes far beyond an update. It’s a modern, AI-powered, and patient-centric platform designed to make preventive care even more accessible, engaging, and secure. With Diagnostyka’s strategic vision and medical expertise, we’ve delivered the product as a technological partner. 

01. From redesign to rebuild

Our goal was not to refresh the look and feel, but to rethink how the app works — technically, visually, and strategically. The challenge was to rebuild the app’s architecture and UX while keeping it simple, intuitive, and fast. The app had to fit existing Diagnostyka’s ecosystem.

02. Engaging users in prevention

Diagnostyka wanted to motivate people to take charge of their health. The challenge was to go beyond transactional features (buying tests, checking results) and create tools that would encourage patients to return regularly and monitor their well-being.

03. Ensuring security and data privacy

Working in the healthcare industry means operating under strict security standards. Every feature — from AI modules to cloud infrastructure — had to be compliant, private, and transparent, giving users confidence that their medical data is safe.

04. Building a seamless partnership

The project required close cooperation between Miquido and Diagnostyka. The challenge was to combine our client’s medical expertise with our product design and engineering excellence — creating a synergy between two teams and disciplines.

01. Reimagined user experience

We rebuilt Diagnostyka’s mobile app using Flutter, ensuring consistency and performance across Android and iOS. The interface was redesigned to be accessible, easy to navigate, and stress-free — especially for users checking medical results. The product was tested with patients to make the experience feel trustworthy and seamless.

02. Innovative preventive tools: LiDia & Profilaktometr

To transform the app into a true health companion, we designed two flagship features.

LiDia, an AI assistant powered by verified medical knowledge from Diagnostyka experts, helps users suggest relevant tests available in Poland — safely and accurately, unlike generic AI chatbots. In this case, AI’s role is to enable easy access to factual information. Thanks to the conversational interface, patients can ask questions about tests and receive clear answers more quickly. 

Profilaktometr, a gamified dashboard feature, visualizes the percentage of completed check-ups and motivates users to be up-to-date with recommended tests. By placing it on the home screen, we turned prevention into a simple, daily habit.

03. Secure, scalable technology foundation

We built the system using Google Cloud Platform and Vertex AI, ensuring enterprise-grade security and flexibility. By integrating Gemini models, we achieved a strong balance between performance, cost-efficiency, and data protection. With Google’s data center located in Warsaw, all information stays within national borders — a crucial compliance and security advantage.

04. Seamless integration with the existing Diagnostyka’s ecosystem

The app was strategically designed as a fully integrated component, ensuring seamless interoperability with core existing medical systems (xLab, CSK, and the patient portal). This scalable integration approach fortified Diagnostyka’s well-performing business strategy by immediately enhancing service delivery without disrupting the efficiency of their core operations.

05. Agile collaboration and shared ownership

Throughout the process, we worked closely with Diagnostyka in an agile and transparent workflow. Together, we held workshops, tested prototypes with real users, and refined the product at every stage. The cooperation between our teams was a genuine synergy — combining Diagnostyka’s medical expertise with Miquido’s product and AI know-how.

01. A new benchmark for HealthTech innovation

The new version of the Diagnostyka app is not just an upgrade — it’s a transformation. It bridges healthcare and FinTech trends, setting a new standard for patient engagement and digital innovation in the European medical market.

02. Empowered patients and improved engagement

With LiDia and Profilaktometr, the app now empowers users to take control of their health through gamification and easy access to trusted information. User tests showed higher satisfaction, appreciation for the simple registration process via mObywatel, and strong motivation to return for future check-ups.

03. Security and compliance by design

All patient data, including test results and AI conversations, is entirely private. The app’s infrastructure on Google Cloud and Vertex AI ensures enterprise-level security, compliance with Polish and EU regulations, and total control over data sovereignty.

04. Long-term partnership and growth

The success of the MVP laid the foundation for a long-term collaboration between Miquido and Diagnostyka. The rebuild demonstrates how Diagnostyka’s vision and business strategy can be effectively facilitated with our technological expertise. The partnership between the two teams — flexible, innovative, and business-driven — sets the stage for continuous product evolution in preventive healthcare.
