The following key aspects apply at all times:-



Correct specimen pot selection

The available sizes of specimen pot for histology specimens are as follows. Please ensure that the appropriate sized pot is used for the specimen taken. The specimen should be covered with a sufficient amount of formalin to allow adequate fixation, the specimen should not touch the side of the specimen pot, or placed such as to alter its’ shape.

Help us to achieve optimum fixation and to provide you with the best possible opinion by using the appropriate sized specimen pot.
