Martha Ward enquires about disinfecting a cryostat after cutting an HIV 
positive specimen. 
I think that is kind of missing the point. Using the Standard Precautions  
procedure (until recently called Universal Precautions) you should consider 
ALL specimens infectious, if they are HIV positive or not. The reason is, you 
do not really know which of your patients is infected, and which are not, and 
with what diseases. Often we do a frozen and then the surgeon adds, as an 
afterthought, "Oh by the way, this patient is infectious". 

We have a biohazard stcker on out cryostat and consider the chamber  infected.
