We discussed this problem of weekend fixation of breast tissue (about 54 hrs in
10% NBF) with our Reference Lab and they reassured us that ER/PR IHC wouldn't
be a problem. However, when ordering Her2, select FISH method instead of IHC.
(Otherwise, if it is fixed for less than 48 hrs we would order Her2 by IHC,
then reflex 2+ to FISH). Any thoughts about this?
