RE: Formalin for processors and HPY billing

From:Tony Henwood

We use 70% ethanol to rinse the formalin prior to processing to absolute ethanol. Decreases the salt build up dramatically. I also thought it prudent to do a warm soapy water and hot water rinse prior to processor solution change.

Subject: Formalin for processors and HPY billing

Dear All:

I am in terested in views on what formalin you use for your processors. I have a Sakura Tissue Tek VIP. We are using Tissue Tek "VIP Formalin" This stops the build up of salts and removes the need to do water rinse. Can anyone tell me how important it is, is regular formalin, with a rinse just as good.  

 I am also interested in optimizing my processing. We have only skin tissue and will be using xylene. What protocols are you all running out there. I am interested to know. My processing is good but there is always room for improvement.

Finally on a completely different note. HPY(the immuno stain), can my pathologist bill for it? Can we make money out of it?

Sorry about the mercenary nature of the final question, remember the patient.

Thanks and have a good weekend.

Yours faithfully,

A. Kevin Williams.
