Gene analysis is used for early detection of genetic and chronic diseases, such as cancer and heart disease. This technology allows identification of genetic changes before symptoms appear, enabling early intervention and effective treatment. Genetic tests rely on a small sample of blood or saliva to analyze the genetic code and assess potential risks. Test results can also be used to design personalized treatment plans tailored to the patient’s genetic makeup. This technology improves recovery chances, reduces medical costs, and raises health awareness, making it a powerful tool in preventive medicine and early disease diagnosis.
