A medical diagnosis is the process of identifying a disease or condition based on a patient's symptoms, medical history, and test results. Healthcare professionals, such as doctors and nurses, use various methods, including physical examinations and laboratory tests, to determine the underlying cause of a patient's health issues. Once a diagnosis is made, it guides the treatment plan and helps in managing the patient's condition. Accurate diagnoses are crucial for effective treatment and can involve collaboration among specialists, such as radiologists and pathologists, to ensure comprehensive care.
