Diagnostic methods are techniques used by healthcare professionals to identify diseases or conditions in patients. These methods can include physical examinations, laboratory tests, imaging studies, and patient interviews. Each method provides valuable information that helps in understanding a patient's health status. Common diagnostic tools include blood tests, X-rays, MRI scans, and ultrasound. These tools allow doctors to visualize internal structures, assess organ function, and detect abnormalities. Accurate diagnosis is crucial for determining the appropriate treatment and improving patient outcomes.
