The Greek etymology of the word ‘Diagnosis’ is to distinguish or discern between two possibilities”. But over time the meaning has been changed to:
the act of identifying a disease from its signs and symptoms, the investigation and analysis of the cause or nature of the situation or condition and the decision reached by a healthcare professional.
Diagnosis is the first and the most important step in any healthcare system as it is used as a tool by Doctors and Therapists to advise a patient on treatment options and future health risks. Diagnosis is also an important tool for the health insurance companies to anticipate a probable medical condition of the policyholder. Sometimes it is mandatory to have a diagnosis to get into certain services, institutions or housing programs.
