'''Biochemistry and Haematology''' - Useful to identify any underlying problems for eg. kidney disease, diabetes. May be useful to assess any underlying organ pathology as a contraindication for use of certain medication.<br><br>

In certain predisposed breeds, a clotting profile (or a buccal mucosal bleed time) may be advisable prior to certain procedures for example oral oncological surgery or in some cases even a surgical extraction.

Bacterial culture and sensitivity is not usually useful from samples taken in the mouth. Many of the pathogens are anaerobic and difficult to culture. There is also a large proportion of naturally occurring, nonpathogenic bacteria and results are not always representative and the majority of the information obtained is of little value. However in long term cases that are non-responsive to treatment, or in cases with an unusual presentation, consider culture.<br><br>

Any mass in the mouth should be biopsied. The mouth is the 4th most common site for tumours. Many tumours in the mouth do not exfoliate well, so cytology has limited benefit.

The information you gain from the histopathologist is only as good as the sample you send. <br><br>

The following steps should be followed in order to obtain a good and diagnostic sample:

The following steps should be followed in order to obtain a '''good and diagnostic sample''':

*A full thickness wedge biopsy should be taken wherever possible

*A full thickness wedge biopsy should be taken wherever possible

*The biopsy should be of a sufficient size

*The biopsy should be of a sufficient size

*Send your sample to an experienced oral pathologist or one with a particular interest in oral pathology

*Send your sample to an experienced oral pathologist or one with a particular interest in oral pathology

*If the results don’t match the clinical picture, discuss this with the pathologist and re-biopsy if necessary

*If the results don’t match the clinical picture, discuss this with the pathologist and re-biopsy if necessary
