Chromosomal Aberration Assay: Unraveling the genetic puzzle to evaluate medical device safety through genetic toxicology

15 April 2024

Medical devices play a crucial role in the healthcare industry, and ensuring their safety is paramount to human health. Genotoxicity assessment, also known as genetox testing, is an essential aspect of medical device development. In the evolving landscape of medical devices, Labcorp’s Chromosomal Aberration Assay plays an important role in the assessment of genotoxic potential of these devices, evaluating their safety at a chromosomal level. Let’s explore the significance of this assay and how this powerful tool can assess potential risks associated with medical devices and human health.

Understanding chromosomes

Chromosomes carry genetic information. They are thread-like structures found in the cellular nucleus. Any alteration from the normal chromosome structure or number within a cell can lead to chromosomal aberrations. These changes can either occur spontaneously or be induced by exposure to chemical or physical agents. The chromosomal changes directly affect the DNA of an organism and are valuable indicators of genotoxicity. These DNA alterations can disrupt the genetic code leading to significant health implications, such as genetic disorders, cancer and other diseases.

Purpose of the test

The main purpose of the chromosomal aberration assay is to identify substances that cause structural chromosomal aberrations. These substances are called clastogens. A clastogen is defined as a mutagenic factor that directly causes breakage of the DNA strand or perturbs the normal DNA related processes, thereby causing DNA breakage in the form of deletion, insertion, or rearrangement of sections of the chromosome. If these DNA breaks are left unrepaired or improperly repaired, these mutagenic processes can lead to cancer.  

Significance in patient safety

The Chromosomal Aberration Assay is a crucial part in the safety assessment process. The meticulous evaluation of chromosomes directly impacts patient safety by determining that the device does not cause any genotoxic harm to the patient. This proactive approach to safety assessment not only helps manufacturers to identify but also to mitigate genotoxic risks through the early stages of device development through the development process and prior to its commercialization.

Trust Labcorp with your genetox testing

Identifying genotoxic agents is crucial for assessing the potential risks they may pose to human health and environment. The Chromosomal Aberration Assay is a powerful tool for medical device safety assessment that provides a granular examination of the genetic material. By understanding how different substances induce chromosomal aberrations, Labcorp can better predict the potential long-term effects on human health. At Labcorp’s genetox laboratory in Bedford, Massachusetts, we understand the intricacies of this test and offer it to sponsors for the evaluation of their medical devices, one chromosome at a time.
