Hello,
My facility is trying to determine whether or not it is necessary to perform weak D testing on Rh negative cord bloods (Rh performed in gel). As far back as our LIS can go, there has never been a weak D identified for a cord blood that originally tested as Rh negative in gel.
I am unsure of how to interpret TRM.40780 "Maternal RhIG candidacy assessment must include the identification of weak-D phenotype newborns".
I know there are previous threads on this topic, but most are quite old. Currently, do you perform this testing at your facility? Any input is appreciated. Thank you!
