Introduction to Risk Assessment
Toxicological risk assessments are prepared to provide a thorough review of the chemicals in your extractables/leachables report. Following ISO 10993 - 17, our toxicologists assess each chemical to establish a margin of safety and determine whether the further testing or analysis is required to reduce the risk.

It represents a substance-specific dose that is unlikely to cause an adverse effect if an individual is exposed at or below this dose every day for a lifetime.
Following the relevant guidelines, experienced toxicologists will use high-quality data and identify the sensitive toxicity endpoint (such as NOAEL, LOAEL, etc.) based on existing information, registered materials or other officially released safety limits, and apply the appropriate uncertainty factor (UF1-UFn) to evaluate the PDE. When necessary, use computer toxicity prediction software (QSAR method) to predict the toxicity.
