[Histonet] validation of lot #'s for IHC & Specials

[Joyce Cline]

We currently pull a control already stained with the old lot # and stain
a control with the new lot # and compare staining. Our paths are saying
you should use the same control block for both the old and new lot #'s
but we don't always have the same block (might have been exhausted)
 
Does anyone keep a control block without exhausting it, for lot
validation?
Does anyone check lot #'s for their special stains. We have a Ventana
NexES Sp. Stainer and we order pre-made kits for our hand staining. Our
paths want us to validate the lot #'s for our specials also.
 
Thanks..Joyce :-)
