We also had problems with gastric bx's and it wasn't a consistent problem. I retrieved them and then stained them H&E and they were much better. It did not seem to matter what you retrieved them with either....very weird. We think it is something with the fixation. I had a problem with bone marrows and it turned out to be, the decal was messed up, but I retrieved them and they stained better. Go figure.... but it worked. My Pathologist also heard about this at a conference he went to. They did not know why it worked either. We do the microwave Steiner now and it works much better. Try the retrieval...good luck.

Subject: [Histonet] warthin starry
I have put this question out once before and I didn't get much for a response so I thought I would try putting it out there one more time. I have an ongoing problem with my Warthin-Starry stain. The peripheral edges of some of the gastric biopsies are not staining. I am also experiencing this same non-staining with the Steiner stain on the Ventana stainer. I have tried reducing the temp on the processor down from 60c to 58c thinking they might be "cooking" on the processor (the H&E's look fine) as well as checking the ph of my solutions. This did not work. Could this be a handling problem prior to fixation in 10% NBF? I am at my wits end. Any suggestions will be greatly appreciated.
Thanks in advance.
