RESUMEN
Analysis of 30 IU of total blood, in which 15 IU of professional blood donors and 15 IU of voluntary blood donors. 20 IU of erythrocyte volume, of them 10 IU were preserved in CPD/S, A, G, M2 (terumor) solutions and 10 IU were preserved in S, Na, G (glucoza 5%, NaCl 9%o with rate of 1:2). The results showed that: the erythrocyte indexes in the blood IU of the volutary blood donors were significantly higher compared to that of the professional blood donors. There was no significant differences of the erythrocyte indexes in blood IU preserved in the international standard solutions until the date of 10, 15, 20 and 30th and in S, Na, G solutions after producing and at the date of 10th at 4 2oC. However, erythrocyte indexes were found to be different in blood IU preserved in S, Na, G at the date of 15th and the following time
