The National Institutes of Health (NIH) Clinical Center in Bethesda, MD, intends to award a sole-source firm-fixed-price purchase order to Siemens Healthcare Diagnostics for one new PFA-100 Platelet Function Analyzer. This notice is for informational purposes only and does not constitute a request for quotations; no solicitation will be issued. The analyzer is needed to replace an unreliable existing unit to ensure uninterrupted platelet function testing for patient care and clinical research. Siemens is the only source capable of providing a compatible instrument that works with existing proprietary cartridges, reagents, and validated methodologies. Interested parties may submit a capability statement demonstrating an equivalent solution by June 24, 2026, at 11:30 AM EST.
