Why did I receive an Explanation of Benefits (EOB) stating that I may be responsible for all or some of the cost of the NeXT Dx test? 

If you have health insurance coverage, you will likely receive an EOB in the mail or via email. An EOB is not a bill. An EOB is an overview of the services that Personalis has provided and a preliminary estimate of the benefits that your health insurance has covered. Our Billing team will work with your health insurance company to determine coverage for your testing.
