Modifier text	What it means
Directed	This component has been collected from a selected donor known to the patient, usually a close relative of the patient. It is reserved for that patient and will come with a blue label specifying that patient’s details. Such components are always irradiated.
Hyper concentrated	The supernatant has been removed from the red cell component and the expiry reduced to 48 hours post-hyper concentration.
Irradiated	The component has been irradiated and the expiry has been reduced accordingly. It will have a RAD–SURE^® label to indicate that irradiation was performed.
Irradiated NEONATAL	The component has been ordered for a neonatal transfusion and has been irradiated. The expiry has been reduced to 48 hours post-irradiation. It will have a RAD–SURE^® label to indicate that irradiation was performed.
Irradiated for IUT	The component has been ordered for an intrauterine transfusion and has been irradiated. The expiry is reduced to 24 hours post-irradiation.
Hyper concentrated/irradiated	The supernatant has been removed and the component has been irradiated. The expiry is reduced to 24 hours post-hyperconcentration or irradiation.
For intrauterine transfusion	The component has been ordered for an intrauterine transfusion. The expiry has been reduced to 48 hours post-application of the modifier (eg, washing).
CMV-negative	The originating donor sample/donation has been tested for CMV antibody and is negative.
Not NAT tested	This component has been released without NAT testing being performed, usually due to extenuating circumstances such as machine failure or specific clinical demand. A disclaimer form will accompany these components.
Low anti-T	The originating donor sample/donation has been tested and anti-T was not detected.
IgA deficient	The originating donor sample/donation has been tested and is IgA deficient.
Secretor plasma Le(b+)	The component is from a Le (a-b+) donor and, as such, is suitable for absorption of Lewis antibodies. Suitable for transfusion.
Not for neonatal use	The component has been deemed unsuitable for neonatal use due to the presence of red cell antibodies (low titre only). It should not be transfused to a neonate.
Phenotype reserve	The originating donor sample/donation or previous testing of donor has had an extended phenotype performed and forms part of a panel of cells reserved for patients with antibodies or where antigen negative blood is otherwise specifically required.
Low anti-A/B	The originating donor sample/donation has low levels of anti-A and anti-B.
Autol release - see disclaimer	This autologous component has tested positive for one or more viral markers but has been released upon request by the patient’s physician. A disclaimer form will accompany these components.
Notes: NAT: nucleic acid technology; CMV: cytomegalovirus; IUT: intrauterine transfusion
