[Histonet] New CAP question ANP.22760

[McMahon, Loralee A]

I think that CAP means that you need to save the slide that you ran from the previous lot and compare it to the slide that you have stained with the new lot number.  To see if they are sufficient diagnostic quality.  Not put both lot numbers on the machine at the same time and then compare the slides?   We run Dako machines and it would be tricky to put both numbers on the same machine.

Although this is my interpretation.

I don't think I can do this with the automated system we are currently
using. Ventana. Does any other Ventana users know if you can do this in
"parallel"

Sorry, I should have included it.

ANP.22760  Are new lots of antibody and detection system reagents tested
in parallel with old lots?  (NOTE: New lots of primary antibody and
detection system reagents must be compared to the previous lot using an
appropriate panel of control tissues.)

Can you give us the wording of that question/checklist item? Laurie

How are IHC labs complying with this question? What is considered an
appropriate panel of control tissues? What do you stain to test your
detection systems?
