A personal reflection on how biological evaluation shaped the author’s life, from life-saving but imperfect neonatal blood bags to growth-hormone therapies and early medical devices, and how these experiences now inform a human-centred approach to designing safer, smarter medical technologies…

Over-extraction in medical device testing often produces results that don’t reflect real clinical use, leading to misleading toxicological profiles, credibility risks, and regulatory delays. By applying clinically relevant extraction methods, reducing measurement uncertainty, and aligning with regulatory expectations, medtech companies…

ISO 10993-12:2021 is a critical but often overlooked standard that defines how medical devices must be prepared and extracted before biocompatibility testing. Proper sample preparation ensures accurate, clinically relevant results and prevents regulatory setbacks caused by false positives, missed risks,…

The latest edition of ISO 10993-1:2025 introduces important updates to the biological evaluation of medical devices, strengthening integration with ISO 14971 and introducing revised contact categorisation and biological effects.

Chemical characterisation is a crucial process in assessing the safety and biocompatibility of medical devices by identifying and quantifying the chemicals that make up their materials. Guided by ISO 10993-18, it ensures manufacturers understand potential chemical risks, enabling informed material…

Reusable medical devices face increased regulatory scrutiny under MDR and FDA expectations, with reprocessing now requiring clear, defensible evidence. Common failures occur in cleaning validation, disinfection efficacy, sterilisation justification, service life testing, and post-reprocessing biocompatibility. Strong validation programmes start with…

Real-world gaps in IFUs and reprocessing workflows demand strategic action from medtech leaders to protect patients and support SPD teams.

Service life validation demonstrates that a medical device continues to perform safely and effectively throughout its intended lifespan. It verifies durability under expected use, maintenance, and reprocessing conditions, supporting ISO 14971 compliance and risk management. By replicating real-world stressors, customised…

Medical device sterilisation ensures patient safety by eliminating microorganisms. Manufacturers must rigorously validate sterilisation methods based on device type. Validation follows standards like ISO 17665 and proves consistent Sterility Assurance Levels (SAL). Clear Instructions for Use (IFU) and proper validation…

At Test Labs we validate cleaning, disinfection, and sterilisation of reusable medical devices to ensure safety, regulatory compliance, and durability. Our insights help medical device manufacturers produce devices that are effective, reliably reprocessable, and sustainable.

Mechanical degradation caused by repeated medical device reprocessing can lead to fatigue, cracking, surface wear, and loss of function. Understanding these risks, and validating durability through service-life testing is essential for safe reuse and regulatory compliance.

Quality testing in medical devices ensures safety, compliance, and performance from concept to market. By verifying material integrity, chemical safety, and mechanical strength, it prevents failures and builds confidence in device reliability. It’s a strategic investment that protects patients, reputation,…

Incompatibility between disinfectants and device materials results in equipment damage and higher HAI rates. Understanding and addressing root causes is essential.

Chemical agents used during medical device cleaning, disinfection, and sterilisation can degrade metals and polymers, leading to corrosion, embrittlement, discoloration, and additive leaching. These changes can compromise performance, safety, and regulatory compliance. Understanding material compatibility, controlling processing parameters, and validating…

Visual degradation after cleaning, disinfection, or sterilisation is often dismissed as cosmetic, but it can indicate deeper mechanical or chemical damage. Identifying and managing surface changes early is critical to maintaining medical device safety, performance, and compliance.

Manual disinfection is essential for heat-sensitive reusable medical devices that can’t undergo sterilisation. Breaking down when, why, and how manual disinfection is used, including regulatory standards, Spalding classification, and critical process controls that medtech leaders must know to stay compliant…

This course is specifically designed for medical device manufacturers seeking to enhance their understanding of laboratory processes and regulatory requirements for medical devices.

Medical device and IVD safety relies on IEC 60601-1 and IEC 61010-1 standards. Understanding MOPP, MOOP and clearances is critical for risk management and regulatory compliance. These standards guide manufacturers in delivering safe, compliant and reliable products.

While Good Laboratory Practice principles were originally intended for non-clinical studies in the chemical and pharmaceutical sectors, their scope has expanded to other industries, such as medical devices.
