| 1 Proportion of Group O SDAP units with baseline antiA andor antiB titres exceeding predefined thresholds: IgM more than 1 in 4, IgG more than 1 in 8.Timepoint: 1 Proportion of Group O SDAP units with baseline antiA andor antiB titres exceeding predefined thresholds: IgM more than 1 in 4, IgG more than 1 in 8. | — |
Secondary
| Measure | Time frame |
|---|---|
| Measured reduction in titre levels (IgM & IgG antiA & Anti B) at same day of collection Percentage of units achieving target safety thresholds ( anti A & Anti B (IgM less than or equal to 1 in 4 & IgG less then & equal to 1 in 8). Optimal ratio & volume of PAS required to reduce titres to acceptable levels Number of PAS treated group O SDAPs used for ABO incompatible transfusions Potential reduction in group-specific donor dependency. Frequency & nature of adverse transfusion reactions, if any Comparison between IgM & IgG titre reduction patterns in response to PAS dilution Timepoint: - | — |
