Basis for Intended Source

CareDx, Inc. has represented in a letter dated June 10, 2026, that it is the sole-source provider of AlloMap Heart and AlloSure Heart testing services. CareDx further represented that AlloMap Heart is the only heart gene-expression testing service available on the market and that HeartCare, which combines AlloMap Heart and AlloSure Heart, is the only combined heart gene-expression and donor-derived cell-free DNA testing service available on the market. Based on the proprietary nature of the required assays and the information currently available to VA, CareDx is the only source known to be capable of satisfying the requirement without substituting different tests or methodologies.

Response Requirements

An interested source must submit sufficient, specific, and verifiable information demonstrating its present ability to perform the complete requirement. Marketing literature or an unsupported statement of capability is not sufficient. The response shall include:

Legal business name, physical address, point of contact, telephone number, email address, Unique Entity ID, CAGE code, and business size and socioeconomic status under NAICS 621511.

Evidence that the respondent can furnish and perform both AlloMap Heart and AlloSure Heart testing services, including any license, ownership right, authorization, or enforceable agreement permitting the respondent to provide the proprietary assays for the entire contemplated period of performance.

A point-by-point explanation of how the respondent will satisfy the attached Statement of Work, including estimated quantities, specimen supplies, collection support, handling and shipping, published turnaround times, result reporting, technical consultation, customer support, invoicing, records management, privacy, and information-security requirements.

Copies or identifying information for current CLIA certification, applicable laboratory accreditation, licenses, and other required professional credentials.

Identification of the laboratory location where each assay will be performed and disclosure of all proposed subcontractors or reference laboratories.

Relevant past performance demonstrating successful performance of the same or substantially similar heart-transplant molecular testing services.

Identification and technical support for any proposed alternative methodology, including clinical validation and a clear explanation of how the alternative meets every functional and clinical requirement without increasing risk, delay, or burden to Veteran patients or VA clinicians.

Submission Instructions

Responses are due no later than October 15, 2026, at 4:00 p.m. Central Time. Submit responses electronically to the Primary Point of Contact identified in the SAM.gov notice (ognian.ivanov@va.gov), please include CareDx AlloMap/AlloSure Heart Sole-Source Notice Response in the subject line. Responses shall be in Microsoft Word or searchable PDF format and should not exceed 10 pages, excluding licenses, certifications, and supporting technical validation. Clearly mark any proprietary information.

The Government will not reimburse any costs incurred in preparing or submitting a response. Submission of a response does not create any right to an award and does not obligate the Government to issue a solicitation, conduct discussions, or award a contract.

Government Determination

The information received will be used solely to determine whether a competitive acquisition is feasible. A determination not to compete this proposed action, based on responses to this notice, is solely within the discretion of the Government. If no timely response demonstrates that another responsible source can satisfy the complete requirement, VA intends to solicit and negotiate only with CareDx, Inc.
