Simple tests can protect future generations:Screening identifies hereditary conditions; counselling supports healthier family outcomes

Genetic Screening and Counselling Can Help Prevent Inherited Disorders in Future Generations Many hereditary and genetic disorders can now be identified before they affect the next generation, thanks to advances in medical science. Health experts say timely screening, pre-marital testing and genetic counselling can help individuals and couples make informed decisions about their health, family planning and reproductive choices. Why early screening matters Timely screening involves undergoing medical tests before symptoms appear. Conditions such as thalassemia, sickle cell anaemia, certain cancers and metabolic disorders can often be detected at an early stage through screening. Doctors say early detection improves treatment options and helps identify people who carry genetic mutations without showing any signs of disease. Since these mutations can be passed on to children, finding them early allows families to take preventive steps and seek medical guidance. How Pre-Marital testing helps Pre-marital testing is a preventive health check conducted before marriage. It generally includes blood group testing, screening for infectious diseases and tests to determine whether either partner carries an inherited genetic disorder. The test is particularly important in regions where conditions such as thalassemia are common. If both partners are carriers of the same genetic disorder, there is a higher risk of passing the condition on to their children. Health experts stress that pre-marital testing is not meant to discourage marriage. Instead, it provides couples with important health information, allowing them to make informed decisions and plan their future with greater confidence. Role of genetic counselling Genetic counselling is a specialised medical service that helps individuals and families understand their genetic risks. Trained counsellors review family history, medical records and genetic test results to assess the likelihood of inherited conditions. The service is especially beneficial for couples planning a pregnancy, people with a family history of genetic disorders, parents of children born with congenital conditions, individuals who have experienced repeated pregnancy loss and those who receive abnormal genetic test results. Experts say genetic counsellors provide both medical guidance and emotional support, helping families understand their options and next steps. Benefits for future generations Healthcare professionals believe that combining screening, pre-marital testing and genetic counselling can significantly reduce the burden of preventable genetic disorders. Early diagnosis often leads to better treatment outcomes, while informed family planning can lower the risk of inherited diseases. Over time, this can also reduce healthcare costs and improve overall public health. Experts say these simple and accessible measures can make a meaningful difference, helping more children be born healthy and improving the health of future generations.
