toxicological risk assessment

ISO 10993 webinar series: Toxicological risk assessment (Part 5 of 7)




The potential of a chemical substance leached from the medical device or material to cause adverse biological reaction is considered as toxicological hazard. Risk is considered as the probability of adverse reaction in response to specific exposure level of the hazard.  

In order to quantify the toxicological threshold such as tolerable intake, tolerable exposure, allowable limit and margin of safety of a hazard that is acceptable for human exposure, a detailed toxicological risk assessment of each and every chemical identified through various methods needs to be evaluated. This, along with the biological studies of medical devices will provide a strong evidence for the biocompatibility of the final device or material.

In this webinar, we will discuss about the toxicological risk assessment of extractables/ leachables from Medical Devices


  • Methods of identifying Toxicological Hazards
  • Derivation of Toxicological Thresholds
  • Factors and Particulars for Toxicological Risk Assessment
  • Reporting of Toxicological Risk Assessment 
  • Q&A
