[Histonet] Tissue Contamination

Thu Aug 29 15:03:02 CDT 2019

I would like to start off by saying that I am a full-time Pathologists'
Assistant with 33 years experience. I started a side company about 15 years
ago to deal with issues such as this. We currently have a heated forceps jar
that by its design greatly reduces the chance of floaters/contaminants.

Even more exciting, we have a hands free, patent pending device coming out
in the Spring 2020 that will near totally if not completely eliminate the
occurrence of contaminants, both at the grossing bench and embedding
station.

I agree with the comments made.
How do Histotechs mitigate the risk?
Do they use water? Do they just place the forceps back into the hot
well/holder at the embedder? What is the best way to ensure safe embedding
by the Histotech?

Although rare, contaminants do end up in blocks. The grosser says it?s the
Histotech at fault. The Histotech says it?s the grosser.

I once inspected a lab and I witnessed the use of a microbiology flame
sterilizer to sterilize the Histotech forceps between biopsies.   Never seen
that before.

tissue embedding stage. It is all about mitigating of risk.

blade and forceps are rinsed in water between cases. I am not aware of any
cross over of tissues between cases when utilizing these practices.
