Re: [Histonet] AFB Stain


Check with your microbiology department. They are probably doing it already.

One difference I've found between doing this procedure on smears vs.
fixed/processed tissue - with smears, there is a 5 minute acid-alcohol
decolorization. With fixed/processed/paraffin embedded tissue, reduce this
to 2-3 seconds. The AFB cells walls have been compromised with the fixative
and alcohols and xylene of the processing.
