5. Quality Control of Blood Storage

All efforts must be made to store and transport blood, blood components and plasma in as safe a way as possible. Important element of maintenance of temperature are :
1) Equipment to store and transport
2) Organisation of staff responsible for maintenance of safe temperature controlled st�rage.
In some of the hospitals, operation theatre maintain a seperate storage space for blood and blood components. The staff of blood transfusion centre shold maintain the storage condtiions in distant storage places also.
Temperature monitoring
The blood storage equipment must have uniform temperature distribution, an alar�i system to detect gross irregularities in temperature and a temperature chart recorder.
In all blood storage equipment, regular monitoring of temperature using good thermometers is essential. A daily temperature recording chart may be affixed on the front door of the refrigerator and an 8 - hourly temperature recording should be done by responsible laboratory staff member.

Maximum and minimum thermometers can also be used to detect how low or hgih the temperature had been. The temperature should be recorded in different shelves on different occasions to ch�ckfor uniformity of temperature.
If blood has to be stored in domestic refrigerator it should never be kept close to the freezer compartment or in the door of the regrigerator due to wide variation in temperature in these parts of the refrigerator.
The temperature recording is a must in a domestic refrigerator whether storing blood units or reagents and test kits. If wide variation in temperature is noted, the temperature may be adjusted using the adjustment knob and storage may be done according to the temperatures in different shelves of the refrigerator.
The outdated blood bags may be sent for bacterial culture, which can also act as a quality control for sterility of blood collection and storage condition.
