We submit a request  form for control material with a positive case, the pathologist approves the case , a copy of the signed request is kept in a notebook and the control logged in the control log. Everytime that block is cut the 1st and last slides are tested.
When we validate antibodies we do run a negative control. We run 13 slides 3 dilutions, 4 methods  1 negative.

Hi All,
   
  I have a few questions regarding IHC. When validating controls and new antibodies do you always run a negative control slide as well? Can anyone share their protocols with me on validating controls, and new antibodies? Any help would be appreciated. Thank you.
