Your results will have no impact on your current life insurance coverage. That said, like other medical tests you elect, a decision to take one or more lab tests made available through Function Health, and the results of those lab tests, may need to be disclosed in an application for insurance coverage, unless prohibited by law, and thus could affect your access to future insurance coverage and the price of such coverage.
