[Histonet] demonstration of asbestos by means of electron microscopy

[Connolly, Brett M]

Yolanda,

Yes it is, TEM is often used for asbestos detection in lung tissue to identify chrysotile and/or crocidolite (mesothelioma-associated) asbestos fibers.

There are a lot of publications out there...

Dear all
 
I am a histotechnologist in forensics, Cape Town, South Africa.
I received a request to show asbestos in lung tissue where there is
definite interstitial fibrosis, but the presence of asbestos is not
clear.
 
Is it possible to reveal asbestos by means of electron microscopy?
 
Usually asbestos is demonstrated using the Perl's Prussian blue
technique, but most times they are elusive.
Could it be because of the sampling site or simply the nature of the
asbestos?
 
Thank you in advance
