Genomic testing involves analysing a patient's whole genome and therefore provides more extensive information. Patients must be made aware of the purposes of these tests, and what they are being carried out for, but also made aware of the potential for these tests to find other, possibly unexpected, results.

In order for patients to provide their consent, they need to be given enough information to make an informed decision. The significance of results needs to be explained and the fact that it may be difficult to predict the significance of some findings and results.

Genetic and genomic information is different to other forms of information used in healthcare in that a patient's test result may also have implications for other members of the patient's family, including their children. Where a condition is diagnosed which may affect other members of the family, a careful discussion needs to take place with the patient to ensure that consideration is given to their confidentiality. Doctors need to ensure they are aware of the GMC's guidance relating to disclosing genetic information.
