What is the purpose of genetic testing?

• A. To analyze an individual's environmental exposures
• B. To study the effects of lifestyle choices on genetics
• C. To determine if an individual has a genetic abnormality
• D. To predict future diseases in the general population

Answer: (C)

The purpose of genetic testing is primarily to determine if an individual has a genetic abnormality. This can involve identifying mutations, variations, or alterations in DNA that may lead to specific genetic disorders or predispositions. Genetic testing can provide valuable information about an individual's health, including their risk for developing certain inherited conditions, and can inform decisions about treatment or preventive measures.

Understanding the presence or absence of genetic abnormalities is crucial for both clinical decision-making and for family planning, as it can help individuals understand their own health and that of their relatives. While the other options touch on important aspects of genetics, they do not directly address the fundamental goal of genetic testing, which is to identify genetic alterations associated with health conditions.
