More than 1,400 patients enrolled across 9 clinical sites; analytical performance testing included 27 individual studies and over 10,000 PCR test cup runs

Analytical data to support concurrent 510(k) submission with CLIA Waiver by Application for point-of-care settings, with submission targeted for Q3 2026

SALT LAKE CITY, July 1, 2026 /PRNewswire/ -- Co-Diagnostics, Inc. (Nasdaq: CODX) ("Co-Dx" or "the Company"), a molecular diagnostics company with a unique, patented platform for the development of molecular diagnostic tests, today announced the completion of clinical and analytical performance studies for the Co-Dx™ PCR Flu A/B & RSV upper respiratory multiplex test on the Co-Dx PCR Pro^® instrument* that the Company currently expects to include in its planned submission package. Completion of these studies represents a significant milestone in preparation of a Dual 510(k) and CLIA Waiver by Application submission to the U.S. Food and Drug Administration ("FDA"), targeted for Q3 2026.

"Completing both the analytical and clinical performance studies for the upper respiratory test is a significant execution milestone for Co-Diagnostics," said Dwight Egan, Chief Executive Officer of Co-Diagnostics. "The FDA 510(k) and CLIA Waiver by Application processes require substantial analytical and clinical evidence, and the depth of the work our team has completed, including 27 individual analytical studies, over 10,000 PCR test cup runs, and a clinical study enrolling more than 1,400 symptomatic patients across 9 geographically distinct US clinical sites, reflects the quality of the submission we are preparing to make. We are targeting submission in Q3 2026 and remain confident in our path to clearance."

Prior to IVD test submission to the FDA for review, medical device manufacturers are required to complete extensive analytical and clinical validation studies to demonstrate that the test performs reliably under both controlled laboratory conditions and its intended real-world use. Analytical validation of the Co-Dx PCR test included over 10,000 PCR test cup runs across 27 individual studies, including studies supporting the CLIA Waiver by Application to allow the test to be used in waived point-of-care settings. This also included a rigorous external multicenter reproducibility study demonstrating consistent performance when operated by untrained operators across multiple sites and instruments.

Mr. Egan continued, "The reproducibility study was designed to evaluate whether performance observed in clinical settings could be replicated across different operators, sites and instruments, and the results support inclusion of those data in our planned FDA submission. That consistency is central to what a CLIA Waiver requires and to our broader vision of bringing accurate, near-patient PCR diagnostics to decentralized settings. This platform was designed to perform at that standard."

*The Co-Dx PCR platform (including the PCR Home^®, PCR Pro^®, mobile app, and all associated tests) is subject to review by the FDA and/or other regulatory bodies and is not yet available for sale.
