Use of ficin to clear up non-specific reactions

[SMILLER]

The following article from Lab Medicine discusses the idea of routinely using enzyme treatment to enhance non-specific (we call them equivocal) antibody reactions.  The idea is that some of the reactions we end up calling non-specific (where remaining significant alloantibodys have been all ruled out) may be actualkly developing significant alloantibodys.

Other than reference labs, does anyone routinely try to otherwise enhance reactions to see if a non-specific pattern turns into a specific one?
