Background and Objectives: It is the responsibility of all blood transfusion laboratories to ensure that donated blood is used efficiently and effectively to deal with unexpected life-threatening. The aim of this study was to assess the efficiency of blood inventory in Blood Transfusion Center during a period 2013-2017.

Methods: We retrospectively examined the adequate blood stock level needed during a period 2013-2017. The inventory storages were recorded for 2 times per week consists of blood stock level and old blood units at 14 days before expired.

Results: The red cell stock level in each year was defined for 7 days or 3 days usage.  The results showed that the stock level lower than requirement for 7 days in 2015 was found in 31 recorded (30.4%), while 3 records (2.86%) was presented in 2017. For the stock level 3 days usage, the shortage of stock level was found only 5 records (5.38%) in 2014. In 2017, the average of old age of red cell (2 weeks before expired) was 16.5% (0.9-25.8%) of inventory and most of them was AB group.

Conclusions: Our Blood Center was successfully maintaining a blood inventory level. Our shortage of blood stock level affected by changing the study program to ASEAN in 2014. However, in 2017 the highest of old blood units were detected. Thus, a statistical report on inventory levels and closely inventory management to reduce the age of transfused blood without a significant increase in outdate is challenge.
