How is that different to doctor currently only using the stethoscope for diagnosis and then telling the patient to come back a few days for a follow up consultation and then referring them to the hospital for further test? The more available medical device doctors can use to assist them in providing the best outcome for their patient the better as the patient and doctor would know they've used everything available to them to provide you the best care, everyone knows no diagnostic tool is 100% correct.....haven't we already discussed this, why are you brining this up again????
