A good quality publication will provide fair and impartial information. It is important that information about genetic testing is presented in a way that enables you to choose what is in your best interests. A publication should be honest and informative. It should not influence you by “promoting” particular tests or by using “shock tactics” to influence your decision about testing.
Your rating should be based on your impression of the information about genetic testing as a whole. The hints will help you develop a “feel” for the balance and bias of the information, but your own judgement will also be important. Here are some additional points to help you:

The information is attributed to an editorial team and their details are provided under About Us alongside information about the producer organisation and the editorial process. The information consists of an overview of each genetic condition, management and treatment options, and an analysis of the advantages and disadvantages of several diagnostic tests, including their accuracy, risks and interpretation.

The implications of testing and the consequences of different decisions following a positive result are outlined and linked to personal testimonies from parents who chose a termination and from parents who chose to continue the pregnancy. The site provides links to online scientific sources and to sources of additional support information. The Home Page includes a statement of the producer organisation’s subscription to international health publisher standards and an endorsement from an independent public health research foundation.
