department at st. Thomas's Hospital going to do a little demonstration on
artifacts and artifacts are quite wide in nature in the histopathology
laboratory and it's a very difficult task to actually demonstrate how you
make artifact but that's exactly what we're going to try and do today and
we've decided to focus on a specific area where artifacts can be created and

today's demonstration will show you how creases and folds and knife marks are
created within a paraffin wax section

right what you've just seen demonstrated is the
action of artifacts in one selective area of histological technique which is
Mike rata me there are many many procedures and techniques that can
produce artifacts in the history pathology laboratory we have just tried
to demonstrate one area for you to give you some idea the range and scope of
artifacts that can be created in any history pathology laboratory is quite
extensive but what we've demonstrated to you today is a very good example of two
of the most common
