Here is the latest and greatest on positive controls in relation to the special stains in a CAP accredited laboratory;

ANP.21400             Phase II	N/A   YES   NO

Are positive controls run routinely on all special stains, with reactivity results documented, and are they verified for acceptability before reporting results?

NOTE:  A positive control slide must be run at the same time as any single or group of slides stained with the same special stain.  The tissue chosen =66or the special stain control slide must be appropriate in type and amount.  Both the control slide and the test tissue slide must be judged technically acceptable before the results of the special stains are reported.
