Bluejay Diagnostics and Argonaut Manufacturing Services Announce Strategic Partnership

ACTON, Mass. and CARLSBAD, Calif., June 02, 2026 (GLOBE NEWSWIRE) — Bluejay Diagnostics, Inc. (“Bluejay” or the “Company”) (NASDAQ: BJDX), a medical diagnostics company focused on near-patient testing for critical care, today announced a strategic partnership with Argonaut Manufacturing Services (“Argonaut”) to support the advancement of Bluejay’s Symphony™ platform.

This partnership is designed to support Bluejay’s broader efforts to establish scalable U.S.-based manufacturing capabilities aligned with its ongoing clinical development programs and future commercialization objectives.

By leveraging U.S.-based manufacturing and distribution capabilities, Bluejay aims to improve operational flexibility, support future market demand, and further enhance its ability to commercialize innovative near-patient diagnostic solutions for critical care settings.

“We are pleased to partner with Argonaut as we continue to advance the Symphony™ platform,” said Neil Dey, President and Chief Executive Officer of Bluejay Diagnostics. “This collaboration reflects our commitment to building a scalable and quality-focused operational foundation as we progress toward key commercial milestones.”
