GENOTOXICITY TESTS Meaning and
Definition
-
Genotoxicity tests refer to a series of laboratory experiments conducted to assess the potential of a substance or agent to cause genetic damage. These tests are designed to evaluate the genotoxic potential of various chemicals, drugs, or environmental pollutants and determine how likely they are to induce genetic mutations or other genetic alterations in living organisms.
Genotoxicity refers to the ability of a substance to cause damage to an organism's DNA or genetic material. It can lead to mutations or structural changes in DNA that may have harmful consequences for an individual, including the development of cancers or genetic diseases. Genotoxicity testing is an essential component of toxicology and risk assessment, as it helps identify potential hazards and evaluate the safety of substances intended for human or environmental exposure.
These tests often involve using various cell types, such as bacteria, mammalian cells, or isolated animal or human tissues, which are exposed to the test substance. Different endpoints are assessed, including DNA damage, chromosomal aberrations, or changes in gene expression. These tests can also provide insights into the genotoxic mechanisms of the tested substances.
Genotoxicity tests are typically conducted as part of the regulatory requirements for the assessment of new drugs, pesticides, industrial chemicals, and other potentially hazardous substances. The results obtained from these tests can guide decision-making processes such as determining safe exposure limits or informing risk mitigation strategies.

Etymology of GENOTOXICITY TESTS
The etymology of the word "genotoxicity tests" can be broken down as follows:
1. Geno-: This prefix is derived from the Greek word "genos", meaning "race" or "kind", and is primarily used to refer to genetics or genes.
2. -toxicity: This suffix originates from the Greek word "toxikos", which means "poisonous". It is commonly added to words to indicate the measure of the harmful or poisonous effects of a substance.
3. Tests: This word comes from the Old French term "teste", meaning "small vessel" or "pot", which was originally used to refer to a piece of pottery used for testing metals or alloys. Over time, "tests" has come to mean any procedure or examination performed to gather information, typically in a scientific or medical context.
