Cut-price genetic tests being provided by NIB, which could unintentionally make them eligible for higher premiums can also prevent them from getting life insurance or insurance payouts.

Concerns are majorly for people who are wanting to apply for life insurance which is sold by NIB also.

According to reports, there was no need for customers to give the results of genetic testing to NIB; however, they may have to provide these details to life insurance or superannuation providers.

According to guidelines of the Investment and Financial Services Association's (IFSA) based on genetic testing, the results given might make people get higher premiums, shorter periods of cover, the exclusion of some medical conditions or a refusal of cover.

Associate Professor Christine Barlow-Stewart from the New South Wales Centre for Genetic Education said, "We're not sure, even as experts, of the reliability of the interpretation of the data that comes out. The risks that are given to you, there are still some questions as to whether we can really understand what that means. I think it is far too early for these tests to be given in such a way."

NIB is offering testing through an American company called Navigenics to people. The service that used to cost $US999 will now cost $US499 ($530).
