Predictive testing is a type of genetic testing that helps determine the likelihood of developing certain inherited conditions or diseases. It is often used for conditions like Huntington's disease or certain types of cancer, where a family history may suggest a higher risk. By analyzing an individual's DNA, healthcare providers can offer insights into potential health issues that may arise in the future. This testing can guide individuals in making informed decisions about their health, lifestyle, and family planning. However, it is important to consider the emotional and psychological impacts of knowing one's genetic risks, as the results can significantly affect personal and family dynamics.
