ISO 22544:2025 - Creating a Unified Language for Laboratory Design

Laboratory Design — Vocabulary

ISO 22544:2025 provides the essential vocabulary underpinning laboratory planning, construction, and operation worldwide. The standard establishes precise definitions for everything from laboratory structures (buildings, modular labs, smart labs) to health, safety, sustainability concepts, and roles within the laboratory environment.

Having a common language is vital for seamless collaboration among architects, engineers, designers, laboratory personnel, and regulatory authorities. By aligning on terminology for adaptability, scalability, and risk management, stakeholders can confidently design and build labs that meet today’s stringent requirements while remaining future-ready.

ISO 22544’s vocabulary covers all aspects crucial for productive, safe, and flexible laboratories: from zoning (separating work and support areas), universal design (accessible to everyone), safety features, and emergency exits, to workflow optimization. This shared framework supports compliance efforts, facilitates integrated project delivery, and enables consistent application of best practices globally.

Key highlights:

• Standardizes language for laboratory design, supporting global best practices
• Enhances collaboration across all roles and project phases

ISO 5649:2024 - Defining Best Practices for Laboratory-Developed Tests (LDTs)

Medical Laboratories — Concepts and Specifications for the Design, Development, Implementation and Use of Laboratory-Developed Tests

As medical diagnostics become more specialized, ISO 5649:2024 provides laboratories with a comprehensive framework to assure the quality, safety, and performance of their laboratory-developed tests (LDTs). Unlike commercially manufactured assays, LDTs are either created or significantly adapted by medical labs for cases where no suitable commercial in vitro diagnostic (IVD) device exists—or when adapted use is clinically justified.

This standard addresses every stage in the LDT lifecycle, from determining the clinical rationale and feasibility, through meticulous test design, analytical and clinical validation, routine use, ongoing monitoring, change management, and eventual retirement. It covers risk management, quality management systems, data documentation, and regulatory issues relevant to LDTs and off-label IVD use—without mandating how to achieve compliance in every technical discipline.

Notably, ISO 5649:2024 supports innovation in diagnostic laboratories by offering clear requirements and best practice guidance, ensuring LDTs are reliable and safe to use—critical for patient care, clinical trials, and precision medicine.

Key highlights:

• Provides requirements for LDT quality, validation, performance, and documentation
• Covers full LDT lifecycle: design, pilot testing, validation, use, monitoring, change management
• Supports regulatory compliance and patient safety, including novel and adapted tests
