Platforms

Web, Desktop

Exact Sciences is a leading cancer diagnostics company dedicated to detecting cancer earlier and guiding personalized treatment through innovative genomic testing. Their platform serves patients, healthcare providers, and researchers across 120+ countries, offering flagship products including Cologuard® for colorectal cancer screening, Oncotype DX® for breast cancer therapy guidance, CancerGuard® for multi-cancer early detection, and OncoExTra® for cancer therapy selection.

Given the critical, health-sensitive nature of the platform, where accuracy, accessibility, and reliability directly affect patient outcomes and provider trust, ensuring the quality of the web experience is paramount. The team required a thorough QA engagement to validate the platform's functional integrity, visual consistency, and metadata accuracy across all major desktop browsers and operating systems.

Our approach

Our engagement

Our QA team was engaged to perform thorough desktop-focused testing across the Exact Sciences web platform, a health-critical environment serving patients, providers, and researchers navigating cancer screening, diagnostics, and treatment guidance. The primary goal was to validate the platform's functional correctness, visual integrity, and metadata accuracy before and during active production cycles.

Functional testing covered the complete range of user-facing flows: navigation, content rendering, form interactions, product information pages, and call-to-action journeys spanning Cologuard®, Oncotype DX®, CancerGuard®, and other key product areas. Every critical workflow was validated for expected behavior, error states, and edge cases across all in-scope pages.

UI validation was executed across four major browsers, Chrome, Firefox, Safari, and Edge, on both Windows and macOS operating systems, ensuring consistent rendering and layout fidelity. In parallel, our team conducted a thorough Alt text and meta attribute audit, identifying missing, duplicate, or inadequate metadata across the platform. Given the medically sensitive user base, accessibility and SEO correctness were treated as first-class quality concerns, not afterthoughts.
