Deborha,

I guess the question to ask is, are the urgent samples urgent enough to 
delay other samples? 

You can always reduce the processing time, but there will be trade offs, 
as you allude to with your coments about size of samples. Small samples 
can be processed very quickly (ie biospy samples are often done in a 
couple hours, but are only 1 mm thick). 

I am assuming you have only one processor. If that is the case you can 
suggest running urgent samples alone on a rush scedule and delaying 
other samples for a normal run. 

The point to make is that in no case should the integrity of any sample 
be degraded by the need to rush certain samples.

Hi ,

We work with fish tissues, mainly Salmonids.  Our pathologist has asked 
if
we can reduce the overnight processing to 16 hours from 21 hours, thus,
enabling him to announce urgent samples late afternoon!!

 We use a series of Industrial Methylated spirit, Ethanol, Chloroform 
then
Paraffin.  Our tissue samples can be quite large (up to 3cmx1cm), 
normally
they are below 5mmx5mm.

Any ideas or comments will be gratefully received.
