Have you ever wondered how blood is being donated? Probably yes. If so, you are welcomed inside.
In this hospital (Russian Clinical Hospital for Children) there are as many as 1500 cots and 150 of them are for children with blood disorders. However, blood is needed not only for use in haematology unit but also in oncology department, reanimation, departments of surgery and microsurgery, transplant department, burns unit, maternity department, etc., etc. Without donated blood most of illnesses would have probably been cureless.
Prior to becoming a blood donor you are supposed to make an appointment with a doctor, fill up a form and go through some tests. Moreover, you must do this every time you will donate your blood.
Your blood pressure will be measured and a doctor will inquire about your health.
