Health 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 tools, including blood tests, imaging studies, and physical examinations, to gather information about a patient's health. Once the necessary information is collected, the healthcare provider analyzes the data to determine the most likely cause of the symptoms. This helps in creating an effective treatment plan tailored to the patient's needs, ensuring they receive appropriate care for their specific condition.
