Documentation is a key aspect of lab work. It is almost like doing the practice without procedures.  Its shows history, continuity and evidence that the work was methodical, approved and sound. Thus it provides evidence based substantiation.

Put all you do in practice in written language and you will be sound with this requirement.

My take

Subject: [Histonet] Special stain control validation- CAP compliance

We validate our control blocks prior to patient use.  We label the slide with the stain, date, and results.  We keep the slides in a file for reference.  Our recent CAP inspection cited us on this because it was not documented on paper.  I am considering challenging this, as I feel what we're doing meets the intent of the checklist question.
What are your opinions?

ANP.21460 Special Stain Controls Phase I Validated tissue controls are required for each special stain.
NOTE: Positive tissue controls assess the performance of the special stain. Special stains are performed on sections of control tissue known to contain components specific to each special stain.
Validation of tissue used as a positive control must be performed and documented before being used with clinical specimens.
