Blood Irradiation

Blood is irradiated in order to prevent a potentially fatal complication of blood transfusion called Transfusion Associated Graft versus Host Disease (TA-GVHD).  Irradiated blood is typically used for immunocompromised patients including:

However, TA-GVHD can also occur in other patients when receiving blood from a close relative.

The FDA recommends that blood be irradiated to a minimum dose of 15 Gy (1500 Rads) and a maximum dose of 50 Gy (5000 Rads).   Typically 25Gy (2500 Rads) is set to achieve this goal.

RadTag® was developed to meet the FDA requirement and indicate whether the delivered dose of radiation is within the specified range.

RadTag® is the only indicator on the market which can verify compliance with the minimum and maximum dose levels.
