Human Factors Validation Testing (HFVT) is a critical step in the development of medical devices, demonstrating that intended users—including physicians, nurses, technicians and patients—can use a device safely and effectively under expected clinical conditions. Human factors validation evaluates real use scenarios to identify critical tasks, potential use errors, and user interface issues that could result in patient harm. Conducted in accordance with the FDA’s 2016 guidance, Applying Human Factors and Usability Engineering to Medical Devices, HFVT provides objective evidence that the device can be operated safely after users receive the intended labeling and training. Early integration of human factors helps manufacturers reduce use-related risks, improve usability, and support regulatory submissions.

Sigma Scientific provides comprehensive Human Factors Validation Testing services to support FDA 510(k) and international regulatory submissions. Sigma develops FDA-compliant human factors validation protocols, performs use-related risk analyses, recruits representative participants, moderates validation studies in realistic simulated-use environments, and prepares validation reports that meet FDA and international regulatory expectations.
