We started using the Provue in 2013. Currently when testing prenatal and maternal patients to determine if a patient is a candidate for RhIg immune globulin or Rhogam, we perform tube and weak D testing. Considering the AABB Std that weak D testing is not required, we looked at dropping it all together (except cords and neonatal testing), The Provue ABD gel card package insert says it will detect nearly all forms of D antigen so we are considering using the Provue result exclusively. A quick survey of other labs with Provues in our area shows most are still using weak D testing to various degrees. If you use a Provue, did you drop weak D testing? Or do you only perform weak D if there is a +1 or +2 reaction in gel as some facilities are doing? thanks.
