And it is also true that some machines are more reliable than others and that we have to decide which to select.

I would like to add my 2 cents worth. When I started IHC it was by hand and
the tech was sure they had put primary Ab, etc on each slide. Then we went
automated with a Ventana ES. We learned the hard way that dispensers may or
may not dispense their contents and that this could vary from slide to slide
on the same run! This is when we began to put a control slide on each
positive patient slide for each antibody run on that patient and block.
Machines make mistakes too.
