Just bring all the information to consult ... but the doctor must see the patient first before making a diagnosis ... If you register, it is better to make an appointment online or by telephone, and then it is more convenient to take the appointment number to the registration office to get the number. But because the patient can't be present, the doctor won't give you any conclusions. The patient had better go in person.
I'm not sure about the hospitals in Beijing, but the Union Medical College Hospital, anzhen hospital and cardiovascular system should all be good.
