analisi biocompatibilità dispositivi medici -White Lab

Perform your biological evaluation with White Lab to ensure the safety of your Medical Device.Our biocompatibility studies are carried out in line with the Good Laboratory Practices (GLP ) and ISO 10993, USP, ASTM, and OECD international standards.

A highly-trained team that is always up to date supports the customer in choosing the most appropriate tests and how to carry out them depending on the device or material to test by drafting Rationales and Operating Protocols.

Biocompatibility studies are fundamental to ensure the safety of Medical Devices. Indeed, thanks to the characterisation of the physical, chemical, and biological response of the product, they aim at highlighting all the potential and foreseeable toxic, physiological, immunogenic or mutagenic risks for human use.

The evaluation of biological safety is part of the general safety and performance requirements for Medical Devices set out in Regulation (EU) No 2017/745 (MDR) and for in-vitro diagnostic medical devices in Regulation (EU) No 2017/746 (IVDR).

During the design phase of the Medical Device, it is therefore essential to devise an appropriate testing strategy for biological evaluation based on the chemical and physical structure of component materials (type of Medical Device), the types of the patient's tissue that will be in contact with the device (invasiveness) and the exposure time (duration).

The reference standards are the ISO 10993 series, the United States Pharmacopoeia (USP), the American Society for Testing and Materials (ASTM) and the OECD series.

Specifically, UNI EN ISO 10993-1:2021 standard describes:
  • The general principles governing the biological evaluation of medical devices within a risk management process
  • The general categorisation of medical devices based on the nature and duration of their contact with the body
  • The evaluation of existing relevant data from all sources
  • The identification of gaps in the available data set on the basis of a risk analysis
  • The identification of additional data sets necessary to analyse the biological safety of the medical devices
  • The assessment of the biological safety of the medical devices
