[Histonet] FW: ASRs

[Pat Zeitlow]

This discussion takes place frequently and I also would like final
resolution.  The following statement is from CAP Advocacy (11/98) and
seems clear enough.  Please let me know if something more current
exists.

ASR FACT SHEET
"The FDA very clearly distinguishes ASRs from Immunohistochemistry (IHC)
reagents (final rule effective Aug. 17, 1998).  The FDA defines IHCs as
"in vitro diagnostic devices...intended to identify, by immunological
techniques, antigens in tissue or cytologic specimens."  Unlike ASRs,
IHCs are labeled by manufacturers with directions for use and
performance indications."

Based upon that, my interpretation and practice has been that
disclaimers are unnecessary on IHC antibodies in general.  It may be
that you could be using antibodies that are worked up with home brew
methods (do not come with instructions and performance indications) in
which case I would assume the disclaimer would be appropriate.  

I look forward to the responses from the group on this.

The disclaimer is necessary if the antibody is labeled ASR by the
manufacturer.   If it is, you must use the disclaimer.    Almost all of
our
antibodies are IVD or ASR and we bill for those.  But, if we have a RUO
antibody (we have 2)  we  do not bill for those immunos.   It's not a
CAP
requirement,  it's a CLIA requirement for the statement and CAP is just
following through with their inspections to see if labs are complying.
