[Histonet] microtomy

[Kim Donadio]

Love your question. Hate to hear that you are having a issue. My two cents follow: 
Yes. The amount of time for a faced block will effect the section thickness. The cells become bloated if they   Sit to long. < feel free to have a Friday laugh on this one. 
Anyway. If you havnt changed the stain in any way or the tech isn't rushing and hard facing causing extrenuated cell artifact and you don't have bloated cells? Could it be possible his eyesight got better or maybe he is mad and wants to pick a fuss? 
I sometimes wish we could post pictures if our issues. I'm wishing you the best.

Within the past month, the hematopathologist has felt the sections are thicker than the usual 3 microns.  I had our service technician  measure the microns and the equipment was cutting as set.  I had the blocks cut on a different microtome and we have seen variations there also.  My question is, does the amount of time on ice make a minor difference in the section thickness?  I know a lot of responses may be the difference in the tech cutting inasmuch as how fast they turn the rotations, etc., but,we have ruled out that variable by having more than one tech cut at the microtome in question. I am stymied as to how to remedy this fluctuation!  This is why we love histology, so many variables to create a problem and why I love histonet, so many techs to help one through a dilemma!!  Thank you!!
