ISO 24884:2026 – IVD Requirements and guidance for electronic instructions for use

For IVD companies and Medical Device companies that has IVD portfolio, this new regulation is Published in Sep 2026

Section 1: Purpose, Scope, And Foundational Architecture

1.1 Document Overview and Industry Imperative

ISO 24884:2026 establishes the first unified global standard for the design, delivery, and validation of electronic instructions for use (eIFUs) for in vitro diagnostic (IVD) medical devices. As global regulatory bodies increasingly shift away from physical paper waste, this standard replaces fragmented, country-specific guidelines with an internationally harmonized technical blueprint.

1.2 The Scope of Digital Delivery

The standard focuses exclusively on the mechanisms of delivery, accessibility, and platform validation for digital instructions. It applies to all deployment architectures, including:

• Web-hosted portals (HTML, PDF)
• Embedded software or instrument screens
• Mobile applications and downloadable offline manuals

1.3 Strict Exclusion of Textual Content

ISO 24884:2026 explicitly maintains a clear boundary between how an instruction is delivered and what it says. The actual technical and safety content requirements for IVD documentation remain governed strictly by the ISO 18113 series (Parts 1 through 5). ISO 24884 dictates the container and the delivery pipeline, not the clinical messaging inside it.

Section 2: Core Technical Requirements & Logistical Backups

2.1 Direct Packaging and Label Signals

Manufacturers cannot deploy an eIFU without explicit on-device signaling. Packaging, device labels, or accompanying quick-start inserts must direct users unambiguously to the digital asset using:

• Harmonized symbols compliant with ISO 15223-1 (the eIFU indicator symbol)
• Direct, human-readable URLs
• Machine-readable QR codes or NFC data links

2.2 Version Control and Historical Tracking

To guarantee clinical safety during product field actions, updates, or medical device recalls, the hosting architecture must incorporate absolute version control. Users must be capable of verifying that the digital revision they are viewing correlates directly with the specific manufacturing lot, batch, or software version of the IVD hardware or assay kit in use.

Transitioning to digital delivery does not legally absolve a manufacturer from physical distribution. A critical cornerstone of ISO 24884:2026 is the mandatory fallback process. If a clinical facility or end-user cannot access the internet, or explicitly requests a physical copy, the manufacturer must maintain a free, reliable workflow to dispatch a printed version within a predefined, restricted timeframe.

Section 3: Environment-specific Implementation Tiers

The standard recognizes that an IVD device used in a high-throughput medical center operates under entirely different constraints than a home self-test. It splits implementation into three distinct environment tiers:

3.1 Tier 1: Professional Clinical Laboratories

Infrastructure Expectations: High-reliability internet, multi-user access, and integrated local networks.

Core Requirements: eIFUs should ideally be downloadable or integrated via local network drives to prevent clinical downtime if external internet access drops. Formats should support multi-device viewing (tablets, desktops, instrument interfaces).

3.2 Tier 2: Near-Patient and Point-of-Care (POC) Testing

Infrastructure Expectations: Fast-paced, variable clinical settings (e.g., emergency rooms, intensive care units, or ambulances) where internet access may be erratic.

Core Requirements: Immediate access pathways are vital. Systems must support offline local caching or quick-scan codes on the physical device itself so a practitioner can retrieve critical testing steps or troubleshooting trees in seconds without a login wall.

3.3 Tier 3: Home Self-Testing (Laypersons)

Infrastructure Expectations: Highly variable digital literacy, basic consumer hardware (smartphones), and no formal medical training.

Core Requirements: Extreme emphasis on UI/UX simplicity. eIFUs must be optimized for small screen layouts, feature clear text-scaling options for the visually impaired, and avoid technical jargon or administrative barriers (such as mandatory user registration) before accessing instructions.

Section 4: Risk, Cybersecurity, And Quality Management Integration

4.1 Risk Assessment via ISO 14971

A digital switch is legally categorized as a change in device design or delivery mode. Manufacturers must execute a comprehensive risk assessment in accordance with ISO 14971 that specifically evaluates digital failure modes:

• Risk of a user accessing the wrong eIFU version
• Risk of clinical downtime during an infrastructure server outage
• Consequences of corrupted files or broken hyperlinks

4.2 Cybersecurity Safeguards via ISO/IEC 27001

Because digital distribution introduces vulnerabilities to malicious interception, the eIFU hosting platform must feature cybersecurity controls mapped against frameworks like ISO/IEC 27001:

Data Integrity: Implementation of cryptographic checksums or secure HTTPS transfers to ensure documentation cannot be altered by third parties.

High Availability: Utilization of redundant servers, Content Delivery Networks (CDNs), and denial-of-service (DoS) protection to guarantee that clinical instructions remain continuously reachable 24/7.

4.3 Validation Lifecycle

The software platform hosting and rendering the eIFU must be formally validated as a quality system component before commercial deployment. Any software updates to the eIFU portal require regression testing to ensure historical instructions remain accurate and retrievable.
