These methods range from physical examinations and medical history reviews to advanced imaging techniques like MRI and CT scans, laboratory tests such as blood and urine analysis, and molecular diagnostics like genetic testing. The goal is to obtain accurate and timely information to facilitate early detection, precise diagnosis, and effective management of health conditions, ultimately improving patient outcomes and quality of life.
