This document serves as Amendment 4 to the solicitation numbered 75D30125R73235, issued by the Office of Acquisition Services, effective from April 15, 2025. The amendment includes key modifications to the solicitation process, specifically suspending the solicitation until further notice, and updating the point of contact (POC) to Vic Veguilla, while removing Jennifer Gartzke from that role. The evaluation of Phase I will continue as samples are received, but vendors are exempt from submitting results concerning specific positive controls—B/Yamagata and B/Victoria. Notably, the advancement into Phase II has been suspended until further notice. All other terms of the solicitation remain unchanged. This amendment emphasizes procedural updates in the context of government RFPs, ensuring compliance and clarity for potential offerors regarding submission requirements and points of contact amidst changing evaluation conditions.

The document outlines a government solicitation for a contract with the Centers for Disease Control and Prevention (CDC) to provide serological assays for the detection and characterization of influenza viruses. The contract spans a base period of one year starting June 4, 2025, with four optional extension periods. The core tasks include performing hemagglutination inhibition (HAI) assays to analyze human serum samples and developing new serology assays. Companies may also implement optional "surge support" testing to respond to unexpected demand. The contract requires compliance with various government regulations, including travel and operational safety standards. The contractor must meet performance-based metrics, such as maintaining high accuracy and timely reporting of results. Deliverables include technical reports, training of CDC staff on assay protocols, and regular status updates. Overall, the document serves as a formal request for proposals, emphasizing the need for high-throughput testing capabilities in response to ongoing public health challenges associated with influenza surveillance and vaccine effectiveness studies. The government is focused on achieving efficient, reliable testing services while fostering innovation in serological assay methods.

The document addresses technical questions regarding a proficiency panel related to serology testing, specifically using the hemagglutination inhibition assay (HAI). It details that the panel will consist of 20 test samples, including both positive and negative controls, and will feature three individual antigens that need separate testing. The primary objective is to determine serum titers against these antigens, with a requirement for back titration of the antigens to confirm their concentration in hemagglutination units (HAU). The matching seroconversion rate is defined by a 4-fold rise in paired samples, and laboratories must report viral titers, calibrated against a strain specified by the CDC. The document also indicates a preference for using turkey red blood cells for testing. This inquiry and response format highlights the specificity required in government RFPs related to public health testing standards and emphasizes compliance and clarity in protocol to ensure effective results from the proficiency panel.
