RE: [Histonet] Immuno Controls

I agree with this completely & this is the practice in our lab.

In my opinion, it is always better for patient safety to have the control
and the patient tissue on the same slide - no matter what platform you are
running (or even if you were running them manually!).  I've used BioGenex,
DAKO, Ventana, and manual methods and I feel it is better for the patient
AND cheaper if the control is on the same slide.    No matter how you are
running your IHCs, there is the slight possibility that the instrument
could falter or you could forget to apply a reagent to a particular slide -
better to have the control on there and you KNOW it worked.  Sure, there is
the argument that you go through more control blocks, but if you align your
chuck every time and are careful, that additional tissue is a small price
to pay for better patient care!!!

I'm sure this discussion must be in the archives but my understanding of
the Ventana Benchmark works is that there is a plunger that presses on a
dispenser bottle to deliver the antibodies and reagents to the slide. If
dispenser bottle is not primed or if there is some type of interference
you would not get any antibody or reagent delivered to your slide. Without
control on each slide, there is no way to know. Is this a legitimate
argument? or is the amount of time and tissue needed to accomplish this too

I used the DAKO autostainer and the cases' sections were placed in slides
already containing a tissue control section in a way that both were
"stained" simultaneously.
  I only used one single control for a whole series of cases when doing
Her2neu, or for research studies for our residents.
