    Biocompatibilidad ISO 10993

Pruebas de biocompatibilidad de productos sanitarios

Los productos sanitarios requieren distintos niveles de pruebas de biocompatibilidad según su clasificación y uso. La principal fuente de directrices sobre los requisitos esenciales en cuanto a seguridad biológica es la norma ISO 10993: Evaluación biológica de productos sanitarios. Esta norma define los productos en términos de su invasión y la duración del contacto con el paciente, y en función de eso determina qué nivel de pruebas de seguridad deben completar con éxito los fabricantes antes de comercializar su producto.

There are several processes to complete prior to putting a product on the market.

  1. Draw up a Biological Evaluation Plan (BEP).
    1. Consider the device application and required toxicological end points
    2. Review all known data and identify any gaps that require further investigation or testing.
  2. Plan and conduct any testing required to satisfy gaps identified.
  3. Use data from chemical and bio testing along with information from the BEP to carry out a Toxicological Risk Assessment (TRA).
  4. Combine the gathered to complete the Biological Evaluation Report (BER).
  5. Submit files to your regulator.


Recent modifications to the requirements have resulted in chemical characterisation combined with risk analysis becoming the primary method of establishing the biological risk profile of medical devices. Read more about ISO 10993 part 18 testing at MET here.

The emphasis should be on carrying out testing only when essential and to use chemical/material characterisation in preference to biological studies. After providing the initial product and component risk analysis MET’s service provides the BEP and proposes a test programme. We will restrict testing to cytotoxicty and materials chemical analysis whenever possible. Our extractables and leachables service is offered at five different levels of intensity, with a selection being made depending upon the device application. Finally, a Toxicological Risk Analysis gives complete confidence in the product.



Check your requirements on the medical device biocompatibility matrix. This guide details the studies to be used if you cannot demonstrate your products safety though risk analysis and/or chemical testing.
