[Histonet] Batch Controls

What do you do if the IHC slides need to be sent to another facility.
Currently we place a control on every slide we run. I know this is using a
lot of tissue but I sometimes have 3 different cases going to 3 different
facilities for patient treatment. Also we stain all the IHC stains for 5
different hospitals. I can't see any way of getting around putting the
positive controls on the slides. With having 14 different Pathologists this
seems to work out best. How is everyone handling this?

As the laboratory Director, I can sign-off on the positive control slides or
my staff can do it since I have delegated this responsibility to them.  We
all use a different color pen to mark the slide(s) "O.K." so we always know
who signed-off on the control slide.  All positive controls are filed by
date (the date is printed on the label).  I believe that we can "back-track"
(using the staining logs) to identify which machine the control was run on
(if needed).

Good Morning and Happy Wednesday to everyone,

For those of you that are running batch controls with your IHC stains I have
a couple of questions for you.

What is your process for review and documentation of the batch control

How do you label/identify this slide for easy retrieval? (Do you identify
this slide by date run or stain run)

Thanks in advance for everyone's help,
