Preparation of the patient

Ensure that the patient is fully informed as to the nature of the investigation to be performed and their consent is obtained.  They should understand what the procedure involves, why they need it and what the consequences may be if the investigation is not performed.

Where a patient has to go away and obtain a sample themselves they should be fully instructed in the procedure for obtaining that specimen.
