[Histonet] Daily H&E Control

You should have a daily H&E control that is run BEFORE any patient
slides are.  There can always be a situation arise (i.e. baskets put in
the wrong place) that can affect the staining outcome.  It's much easier
to correct on a control than have to either de-stain and re-stain or
recut patient tissue.  We used to use the patient's slides as controls
until we got the system better.  We use skin, placenta, tonsil, appendix
and uterus as a control that we place in one block.  This gives us a
broad range of stain quality.  We grade the slide for quality as HT's
and record it for our paperwork.  If it passes for us, we stain the
patient slides.  The pathologist gets the control slide as well and
signs off on his paperwork before reading the slides received.

Howdy fellow Histo Techs,


  I am hoping to get an answer from everyone regarding C.A.P. and the
rules about a daily H&E control.  This year will be the first one for
our lab with CAP, I want to know if there is a regulation about having a
daily H&E control to view and if so what tissue do they want used.  Up
till now each day I give my Pathologist a QC sheet to fill out and I
make any changes the next day if there are any problems.  My pathologist
use the daily slides as a control.  Is this enough or do I need to have
record of a control separate from my daily workload?  Thanks in advance
for you help.
