[Histonet] Frozen Section controls

[Sheila Haas]

Here's a new one on me. At recent inspection I was told we should be running a frozen section control slide with our metachromatic stain daily. The inspector was at an off-site facility where we do not have capability of keeping tissue frozen from one day to next not to mention that the metachromatic stain is not permanent (he told me we had to hold slides for 2 years). I also explained that our pathologists do indicate acceptability of stain daily but he said that was not sufficient since the pathologist was looking at patient tissue instead of control tissue. When I explained issue of inability to keep tissue frozen (we have numerous off-site locations) he said to cut an initial, superficial slide of patient tissue to use as control then proceed with patient frozen section after approval of stain. Any one heard of this? Seems a bit much to me.
