The ARC uses E7001, E7002, E7003... are PAS platelets only, not psoralen treated. We have yet to build the psoralen treated product codes into our system.

We are also using the Rh+Kell assay to type donor units. We hope to be able to find R1R1 and R2R2 units for our patients with antibodies rather than relying on our blood supplier.

Is anyone running the assay for Rh and Kell typings on the Tango and what are you using for QC material? Thanks!

We don't require a consent to transfuse RhIg like we do for RBCs and other products.. At our institution, they are considered medications. However, a patient is always able to refuse treatment at any time.

We don't have a full Rh phenotype on the maternal sample but she is Rh positive and E, c negative. The baby is male.

We treat our warm auto patients the same as all the rest. New samples are worked up every three days, regardless of whether or not they have been transfused. Exceptions are cleared by our pathologists.

We recently had a baby born to woman with an allo anti little c. We believe the baby is Rh negative but weak D status has not been confirmed due to a positive DAT (2+). The Rh control tube and the weak D tube were equal in strength to the DAT. The cord cells were typed as litle c positive. If the baby is confirmed to have passive anti c by antibody screening and required a red cell transfusion, would it be acceptable to transfuse Rh positive RBCs that lack the little c antigen because formation of an allo anti D is unlikely? Is anyone aware of plasma exchange being used as a method for removal of maternal antibody in a neonate? Thanks for any thoughts you may have. Terry

At my health system, we automatically perform a delayed transfusion workup when a patient's antibody screen changes from NEG to POS, when a new antibody is identified in a patient with previous antibodies or when the DAT strength increases during a 14 day period following transfusion with RBCs. This protocol involves retesting the original sample to include ASC, AC, DAT. We also pull the segments from units transfused, perform antigen typing and perform crossmatches on the pre and post samples. We were wondering if other transfusion services perform this type of extensive workup. Thanks!
