It was statistically revealed from the questionnaries that the present status of blood banking in 13 countries (Aruba, Austria, Bangladesh, Bermuda, Egypt, United Kingdom, Greece, Kenya, Norway, Singapore, Switzerland, U. S. A. and Zimbabew) was investigated.
Only 2 countries (Austria and Bermuda) had not standard for blood banking. It was considerably interested enought to know there was the special qualification system for blood bank technologysts only in U. S. A. and Zimbabwe.
In all countries, ABO typing test was determined by using both cells and sera. And also Rh typing test was indispensable. Patients' irregular alloantibody screening test is nearly performed using antiglobulin test in all countries.
We knew that immediate spin procedure was used to the patient's sera without unexpected antibodies only in United States, but antiglobulin test was usually used in the other all countries.
Medical education and standardization of technique for blood banking are desired in order to establish safty for blood transfusion.
