Why are there some circumstances in which insurers are allowed to ask for the results of predictive genetic test results?

Anti-selection is a risk that insurance companies face. Anti-selection occurs when someone who is buying insurance has access to more information than the insurer and, as a result, the insurer underestimates the risk of insuring that person. The Code on Genetic Testing and Insurance ensures that the insurance industry has protection against levels of anti-selection, which can threaten the insurers business models and make insurance more expensive for all consumers by allowing some limited access to predictive genetic test results for the most expensive policies.
