Attachment 3 - Redacted Justification and Approval.pdf

This document is a Single Source Justification (Simplified Acquisition) for leasing a Sysmex XN-550 Hematology Analyzer for the 28th MDG Laboratory at Ellsworth Air Force Base. The document details why the Sysmex XN-550 is the only viable option, highlighting its unique capabilities such as six-part differential analysis, compact footprint (17.72" W x 25.98" D x 17.72" H), and ability to sample less than 26 µL of blood using fluorescent flow cytometry technology. The analyzer enables critical functions like early cancer cell detection, streamlined lab workflow, and interoperability with regional healthcare partners including Monument Health and Veterans Affairs hospital.

The procurement is a lease for a base period plus four option years, with the 28th Contracting Squadron conducting the acquisition. The justification emphasizes that market research, including queries of GSA Advantage and sources sought, supports sole sourcing the Sysmex XN-550 due to its proprietary reagent system, unique measurement methods, and specific compatibility with existing laboratory infrastructure. The contracting officer determined that a single source is reasonably available, with the document signed by Joshua A. Johnson on 05-May-2025, indicating the planned acquisition timeline.
