Diagnosis is the act of identifying a disease or condition based on symptoms, medical history, a physical exam, and test results. It can also refer to analyzing a situation to reach a reasoned conclusion. In medicine, a diagnosis names the illness or disorder, while in everyday life or business it can refer to a judgment about a problem or trend. The word comes from Greek dia- through and gnosis knowledge, signaling knowledge gained through careful observation and deduction. Understanding diagnosis helps you discuss health with doctors and talk about decisions and uncertainties with more clarity.
