What are non-human methods of medical diagnosis called? For example, a cat scan or blood work vs a physician's verbal shot in the dark during a ten minute office visit? To narrow the question this is specifically for diseases.
As far as I know, there is NO non-human medical method for a definite diagnosis of diseases accepted in any well known medical center as of 27. 09. 2016.
Medical history and physical examination are performed by doctors. X-ray, CT, MRI, lab tests or even calculations performed by computer programs are usually ordered and interpreted by doctors. It is not a CT machine that tells you a diagnosis, it is a doctor who knows how to read a CT image and make a diagnosis from it.
Sometimes, you may be able to self-diagnose a disease, but this is still human diagnosis.
Related terms are "diagnostic robot," "computer diagnostic tools," "diagnostic software," "machine learning," etc.
There isn't always A test that can definitively diagnose a disease. Sometimes it takes a combination of tests and the doctor's knowledge of the possibilities for your symptoms. If your dr doesn't listen to you, find another one who will. That isn't always easy as I can attest, but it's worthwhile trying.
