Importance of extraction vessel shape in medical device testing: A GeneTox case report GTA 2025 – The in vitro Chromosomal Aberration Test (CAT) Assays play an instrumental role in the assessment of genotoxic potential of a new medical device. The CAT Assays identify substances that cause structural chromosomal aberrations, called clastogens, which directly cause DNA break(s). Medical devices are made using different materials and defining specific doses of the substance(s) of interest is impossible, thus their fluid extracts are prepared, making device extractions a critical factor for…
