Point me to a reference to counter this request."
Hi Mary Ann - First of all, my sympathies. This is the kind of craziness that
can give a pathologist a bad name. Secondly, what does he call a patient
positive? Positive for what? LOL, JK. In response to your question, here are
the ONLY 2 requirements for Cytology stain QC, straight from the latest CAP
list. See below. As one can see, nowhere does it require any type of patient
control, only a documented assessment of the stain quality, on "actual case
material" CAPs words, not mine. Good Luck! Terri

CYP.03925 Stain Assessment Phase I
Cytology stains are assessed at least annually to ensure their proper
storage and acceptable quality.
NOTE: Cytology stains undergoing a daily technical quality review are exempt
from an annual assessment.
Most stains used in the cytology laboratory are not subject to outdating, so
that assignment of expiration dates may have no meaning. The acceptable
performance of such stains must be confirmed at least annually by technical
assessment on actual case material, and as part of the evaluation of
cytopathology cases. Where applicable, expiration dates assigned by a
manufacturer must be observed.
Evidence of Compliance:
✓ Written procedure for stain assessment AND
✓ Records of assessment of appropriate quality of each cytology stain in
use
CYP.04300 Daily QC Phase II
Daily QC Phase II
There are records of daily review of the technical quality of cytologic
preparations by the pathologist or supervisory-level cytotechnologist.
NOTE: The technical quality of cytologic preparations must be checked daily
(on days processing occurs). This includes checking all stains for predicted
staining characteristics each day of use. This check must include all of the
types of preparations seen that day such as cytospins, cell blocks, and liquid
based preparations.
If preparation and staining is performed by a different laboratory, there must
be a procedure for the laboratory performing the preparation and staining to
verify the acceptability of the quality of preparations and the acceptability
of controls (if needed) before transfer. Records of this verification must be
readily available to the laboratory performing interpretations. There should
also be a mechanism for feedback from the interpreting laboratory to the
laboratory that prepared the slides of any issues with the preparations.
