You don't need health information to buy non-health insurance, such as auto insurance, annuity insurance and property insurance. If you are insured with health insurance such as medical insurance, critical illness insurance and cancer prevention insurance, you need health information, so that insurance companies can reduce the probability of insurance claims and underwriting risks.
In addition, if accident insurance is insured, some products also need health notification, but the notification terms are relatively loose, in fact, the specific product insurance rules shall prevail.
