The below list explains the types of label modifier texts and their clinical indications.
- For intrauterine transfusion
-
A hyper-concentrated red cell component with a haematocrit of 0.70-0.85. After preparation, the expiry is reduced to 48 hours and the component must be irradiated before use.
Once irradiated, the component must be used within 24 hours.
- CMV negative
-
The originating donor sample/donation has been tested for CMV antibody and is negative.
- Not NAT tested
-
Due to extenuating circumstances (e.g. machine failure or specific clinical demand), this component has been released without NAT testing being performed.
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 an Le(a-b+) donor and contains soluble H and Lewis antigens (and A or B antigens if the donor is group A or B). May be used to neutralise a recipient’s Lewis or A or B 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/B haemolysins.
- 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.
