DHF Review & Remediation for Regulated Software

A weak DHF does not fail quietly.

It fails during submission.

Frelong Health provides structured DHF Review services designed to assess, strengthen, and defend your product documentation before regulatory scrutiny exposes gaps. Our review integrates risk alignment, lifecycle traceability, and verification defensibility into a clear, actionable analysis.

From structured gap reports to full hands-on remediation support, we help you transform fragmented documentation into a coherent, regulator-ready system.

DHF Review and Remediation Advisory
DHF Remediation

Make it defensible.

  • Looking up at a geodesic dome structure against a clear blue sky with sunlight.

    Structure It.

    A Design History File is more than a document repository.
    It is the technical story of how your product was engineered, controlled, and validated.

    Our DHF Review begins with structured traceability and risk alignment. We assess your framework against ISO 13485 and IEC 62304 expectations, evaluating whether requirements, risk controls, verification evidence, and configuration records are logically connected and regulator-ready.

    This is not a surface audit.
    It is structural analysis.

  • Smartphone placed on a black surface with a disposable face mask behind it. The smartphone screen displays a health app with information about COVID-19 risk status and safety guidelines in German.

    Validate it.

    Regulators don’t review documents in isolation — they assess decision logic.

    We examine whether your documentation supports the engineering decisions behind your product. From requirements traceability to risk-to-test mapping, we identify gaps that could weaken submission defensibility or raise inspection findings.

    You receive:

    • A written gap analysis
    • Prioritized remediation actions
    • Traceability improvement recommendations
    • Risk alignment assessment

    Clarity replaces uncertainty.

  • A large group of soldiers in uniform marching in formation during a parade, with rifles on their shoulders and a dusty field beneath them.

    Defend it.

    A DHF must withstand regulatory scrutiny — not just exist.

    For teams that require deeper support, we offer hands-on remediation and structured consulting to close gaps, realign documentation, and restore lifecycle integrity. We work directly with engineering and quality teams to rebuild traceability, strengthen verification evidence, and implement governance discipline where needed.
