Abstract
Background and Objectives
In Iran, there is self-sufficiency for blood and blood components ensured  by the widespread system of Iranian Blood Transfusion Organization (IBTO). To give a more comprehensive view, the status of blood collection, distribution, and the data on the discarded units in hospitals and blood centers in Iran from 2009 to 2015 were analyzed.
 
Materials and Methods
In this descriptive and retrospective study, all of the blood collection and blood processing centers over the country (totally 214 centers) collected the relevant data, registered them in the data base, and reported to the headquarters of IBTO.
 
Results
During the study period, the mean production percentage rates of RBC, FFP and PC were 94.8 ± 1.9, 83.4 ± 1.9, and 50.7 ± 4.4, respectively. The mean distribution percentage rates of RBC, FFP and PC were 95 ± 2.8, 41 ± 5.1, and 79 ± 2.7, respectively. In addition, 11.1 ± 2.8%, 4.8 ± 0.8%, 1.4 ± 0.2% and 2.8 ± 0.2% of WB, RBC, FFP and PC in order accounted for the returned units.
 
Conclusions 
This study provides information about the status of blood collection, and components preparation and distribution in Iran. It seems that due to the improvement in blood component usage, the number of distributed and returned units has decreased.
