YY/T 0870.2-2019 in English

This standard outlines the procedures and requirements for conducting in vitro mammalian cell chromosome aberration tests as part of genetic toxicity testing for medical devices. It provides detailed guidelines on experimental design, sample preparation, test conditions, and data analysis. The standard ensures consistency and reliability in assessing the potential of medical devices to induce chromosomal abnormalities in cultured mammalian cells. It covers key aspects such as cell culture techniques, exposure protocols, and criteria for interpreting test results. The document also specifies the necessary documentation and reporting requirements to support the validity of the test outcomes. This standard is intended for use by laboratories and regulatory bodies involved in the evaluation of medical devices for genetic toxicity risks.
