RHIG evaluation using Rh or fetal cell detection methods

[lab217]

Do any laboratories include "disclaimers" when resulting evaluations of RHIG in the presence of  maternal antibodies (ie. ABO incompatibilities).  In the limitations section of the rapid screen (metal-maternal bleed screen) package insert, it identifies the potential of removal of fetal cells by the maternal antibody resulting in a false negative reaction in "any" detection method.  How are other blood banks handling this?

[Dansket]

We don't.  Since immunohematology is not an exact science, one could make a case for putting some sort of disclaimer on every test result we produce.
