Medical diagnosis

A medical diagnosis (an. Greek δια-γνωστικος — able to recognize) is when a doctor finds out what is making someone sick. Sometimes doctors can diagnose a sickness by asking the person questions and looking at the person's body. Sometimes doctors do tests. Tests can mean taking a small bit of blood, urine, or tissue which is sent to a hospital laboratory where it is tested. X-rays are another form of test. Tests are ways to see how the body is working.

Medical diagnosis

When a diagnosis has been made, the doctor may recommend treatment.

Process

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.

Laboratory examination methods include general clinical tests, which include a general blood test, a general urine test, and a stool test. Laboratory methods of examination also include biochemical methods of examination, during which the level of glucose, creatinine, urea, bilirubin, liver enzymes, blood lipids is determined; coagulogram, which analyzes the indicators of blood clotting; blood hormone tests; determination of tumor markers; tests of blood and other biological materials for infectious diseases; allergological, toxicological, cytological and parasitological examinations.

Instrumental methods of examination include X-ray, endoscopic, ultrasound, methods of recording the electrical activity of organs (including ECG and EEG) and a number of other methods of examination.

To diagnose disorders of some systems and organs, methods of recording the electrical activity of organs are used, which include, in particular, ECG and EEG.
