    ¡¾Abstract¡¿ AIM: To study the distribution of blood types of the free donors and recipients in a certain hospital in Xi¡¯an area. METHODS: The blood types ABO of the free donors between 1999 and 2002 were tested with paper plate and the blood types of all the recipients in a certain hospital were surveyed by gel test. The amount of blood, stored and needed, was put into a computer for later statistical analysis. RESULTS: The distribution and the proportion of blood types of free donors changed remarkably compared with those of the previous paid donating population in Xi¡¯an. The amount of type B increased while that of type O decreased (P<0.01). The collected blood could roughly meet the clinical need and the hospital sometimes had to turn to other blood banks for help. CONCLUSION: The proportion of blood types of donors has changed in Xi¡¯an area. ......
