The process of diagnosis begins from the very beginning of the patient's examination in a medical institution or during a call to the doctor at the patient's place of residence. Diagnosis of the disease begins with the collection of medical history. After collecting the anamnesis, the doctor examines the patient, during which he performs percussion and auscultation of the patient, palpation of the disease, measures the patient's blood pressure, heart rate and respiration rate, and measures the patient's body temperature.
