ABSTRACT
This chapter considers post-natal genetic testing and screening, although it is clear that problems also exist in respect of testing which occurs pre-implantation or pre-natally. The genetic testing of children, therefore, is even more complex than that of adults. Both the rationale for, and the sequelae of, testing are infinitely more problematic in these cases, even if some good comes out of the results. Equally, any genetic testing will be included, whether it is carried out as a screening test in the community as a whole or whether it is offered to individuals in specific families. For those who would argue that testing for childhood-onset conditions is permissible, the rationale seems to be the support which could potentially be provided to the child. Yet, these same commentators are generally opposed to testing for late-onset conditions.
