Disease diagnosis is the process of identifying a disease or condition based on a patient's symptoms, medical history, and diagnostic tests. Healthcare professionals, such as doctors and nurses, use various methods, including physical examinations, laboratory tests, and imaging studies, to gather information about a patient's health. Accurate diagnosis is crucial for effective treatment and management of diseases. It helps in determining the appropriate medications, therapies, or interventions needed. Early and precise diagnosis can improve patient outcomes and reduce the risk of complications associated with untreated conditions.
