chromosome aberration assay

A chromosome aberration assay is a laboratory test used to evaluate whether a substance causes changes or damage to chromosomes—the structures that carry our genetic information. Scientists expose cells to the substance and then examine their chromosomes under a microscope to identify any abnormalities, such as breaks, gaps, or rearrangements. This test helps assess the genetic toxicity of chemicals or drugs, indicating potential risks of genetic mutations or cancer. It is an important tool in safety testing to protect health by understanding how substances may affect genetic material.
