Please note that all direct patient orders will be processed as cash payments in advance, at the industry’s lowest maximum out-of-pocket cost of $249 per breath test. This streamlined approach ensures you have access to our leading diagnostics without the wait or paperwork associated with insurance submissions. For direct orders, CDI will not submit claims to insurance. This initiative is part of our commitment to providing accessible and high-quality diagnostic care directly to patients nationwide.
