Before a medical examination to assess fitness for entry into the services, candidates are asked to declare any family history of Tuberculosis, Diabetes, Mental Health Disorders, High Blood Pressure, Heart Disease and any other serious illness. While a family history of obesity and epilepsy is not specifically asked about, it may be declared under ‘any other serious illnesses'. If there is a concern that the family history may include conditions with a significant hereditary component, such as Anderson-Fabry's disease, and where there is a strong likelihood of it being passed through the family to the candidate, further inquiry will be undertaken to define the likelihood of the inherited disease manifesting during service. If there is such a risk, the candidate may be referred for a further specialist opinion or rejected for entry, irrespective of whether they have signs, symptoms or a formal diagnosis of a disease at the time of the medical. The Department relies on family history as a screening tool and does not ask for genetic data or require genetic testing. However, should a candidate declare previous genetic testing for a condition then that information would be factored into a fitness decision as relevant to the candidate's health in the future.
