Review Questions

• How does genetic screening impact healthcare decisions for individuals and families?
  • Genetic screening significantly influences healthcare decisions by providing crucial information about potential genetic disorders. For individuals and families, the results can guide treatment options, preventive measures, and even influence reproductive choices. Knowing their genetic risks allows families to prepare for potential health issues or consider alternative options if they choose to have children.
• Discuss the ethical implications of genetic screening related to privacy concerns.
  • The ethical implications of genetic screening primarily revolve around privacy concerns regarding individuals' sensitive genetic information. There is a risk that this information could be misused by employers or insurers, leading to discrimination based on a person's genetic predispositions. Therefore, strong safeguards must be implemented to protect personal data and ensure that individuals maintain control over who has access to their genetic information.
• Evaluate the role of informed consent in the context of genetic screening and its effect on patient autonomy.
  • Informed consent is fundamental in the context of genetic screening as it empowers patients with knowledge about the testing process and its implications. Ensuring that individuals fully understand the risks and benefits associated with genetic testing enhances patient autonomy by allowing them to make informed choices about their health. This process also reinforces ethical practices within healthcare, fostering trust between patients and providers while protecting against potential misuse of sensitive information.
