The RTG25 (Gamma) and RTX25 (X-ray) indicators are designed for 35 Gy central dose delivery. In addition to confirming the central dose, these indicators also verify that the dose is over 25 Gy, but less than 50 Gy, in accordance with regulatory agency safety guidelines.
Blood is irradiated in order to prevent a potentially fatal complication of blood transfusion called Transfusion Associated Graft versus Host Disease (TA-GVHD). For optimal patient safety, it is necessary to confirm that blood products have been irradiated according to standard guidelines. Failure to verify compliance with these guidelines can pose a risk to patients.
- Some guidelines (e.g. USA and Canada) require blood to be irradiated at no less than
15 Gy and no more than 50 Gy. - Other guidelines (e.g. EU, UK and Australia) require blood to be irradiated at no less than
25 Gy and no more than 50 Gy.
Proper verification of irradiation is important. Irradiation dose will vary depending on where blood products are placed in the irradiator and how many blood products are irradiated at one time. Operator and machine error can also lead to under-irradiation or over-irradiation of blood products.
RadTag® irradiation indicators were developed to meet these guideline requirements and are specially calibrated to verify that the dose of irradiation delivered falls within recommended ranges. RadTag® indicators offer the best final validation that irradiated blood is safe to transfuse. No other indicator can offer our quality and assurance. It’s for this reason leading irradiator manufacturers recommend RadTag®.
RadTag® Irradiation Indicators are manufactured under a Quality Management System that is registered in full compliance with ISO9001:2015 guidelines.
