12.7 Blood Bag Tracking
Use Case
RFID technology can be widely adopted in medical field. One of the applications is blood bag
tracking and blood type verification for transfusion.
Current Approach
Blood bags in blood banks are managed manually or using barcode system. Real-time visibility
of inventory data is not available.
Suggested Approach
Before transfusion, the nurse can check the blood type contained in blood bag against patient’s
blood type by cross checking the RFID tags on both the blood bag and patient’s wristband. In
this way, chance that a patient being transfused the wrong blood type due to human error is
greatly reduced. Moreover, by equipping RFID read points in the blood bank, real time
inventory data can be grasped, giving medical staff real-time visibility to inventory level and
status.
Recommendation
One of the major challenges in implementing RFID system for blood bag tracking is the liquid
content inside blood bag, as fluid can degrade the radio frequency signal. However, with CSL
CS-777 near-field antenna, this problem can be overcome since it can achieve outstanding
performance when reading and writing tags on container with different contents even liquid.
