Re: Loss of small biopsies ...
|From:||David Anderson <firstname.lastname@example.org>|
In Dallas, we used nylon biopsy bags for things such as currettings, and
sponges for all other small specimens. The PAs liked the bags because they
could also act as filters - just poured it in and wrapped it up. We did seem
to get a lot of carry-over with the sponges - we used the blue ones and the
xylene on the processors would turn blue - but embedding went much faster
because we didn't have to stop and unwrap things. While embedding, however,
the cassettes need to be kept hot enough to keep the paraffin completely
melted. If the paraffin starts to solidify around the sponges, it can be
difficult to distinguish tissue from solid bits of paraffin.
Here in Riyadh, we wrap our small biopsies in cut-up pieces of paper towel,
something I had never done before, but they seem to process OK and are
easier to unwrap than lens paper.
