Re: control slides

From:Barbara Stancel


We cut about 300-500 AFB or fungal control slides at time. All of the other 
stains we perform are also cut in mass. We store them slide-to-slide in the 
empty new slide boxes that have been labeled and dated. We have never had 
any problems with their staining. Some of our more obscure controls may sit 
for several years.  If we have problems, we can usually trace it to poor 
technic or expired solutions.

This does not apply to IHC controls.

I have a question on control slides and how long can you keep them. I've cut 
over a 100 slides with AFB positive tissue and over 100 fungus positive 
tissue. Is it true that these organism will dry out and be unable to take up 
the stains.     Thanks in advance.       Cynthia
