## Exhibit 99.1

**Exhibit 99.1**

**Bluejay Diagnostics, Inc. Announces Completion of 624 Patient Enrollments in SYMON-II Pivotal Clinical Trial**

Acton, Massachusetts — April 7, 2026 — Bluejay Diagnostics, Inc. ("Bluejay" or the "Company"), a medical diagnostics company focused on rapid, near-patient testing, today announced the successful enrollment of 624 patients in its ongoing SYMON-II Trial, a pivotal clinical study evaluating the Company's Symphony™ platform for interleukin-6 (IL-6) testing in critical care settings to determine patient acuity for sepsis triage and monitoring.

The SYMON-II study has a target enrollment of 750 patients, and the Company expects to complete enrollment within the next 2 to 3 months, subject to site activity and patient flow.

Importantly, the study's inclusion and exclusion criteria have not caused a significant number of patients to be excluded from enrollment.

"This milestone reflects the strong execution by our clinical team and the continued commitment of our investigators and clinical partners," said Neil Dey, CEO of Bluejay Diagnostics. "Reaching 624 enrolled patients positions us well to complete enrollment in the near term, bringing us closer to delivering meaningful clinical insights that could improve outcomes in critical care. We are particularly encouraged by the fact that study's inclusion and exclusion criteria have not caused a significant number of patients to be excluded from enrollment."

The SYMON-II trial is designed to support the clinical validation of Bluejay's Symphony™ IL-6 test, which aims to provide rapid, near-patient results to aid clinicians in assessing patient severity and guiding timely decision-making in acute care environments.

With enrollment nearing completion, Bluejay anticipates progressing toward the next phases of clinical validation and regulatory submission activities, consistent with its broader strategy to advance near-patient testing and real-time monitoring in critical care settings, where timely decision-making is essential.

**About the Symphony IL-6 Test:**

The Symphony<sup>TM</sup> Test platform is designed to determine patient acuity for triage and monitoring based on the measurement of a specific biomarker. The Symphony<sup>TM</sup> IL-6 Test to determine patient acuity for sepsis triage and monitoring ("Symphony<sup>TM</sup> IL-6 Test") is currently Bluejay's lead product candidate.

 

*Note: Investigational device. Limited by United States law to investigational use.*

**About the SYMON Clinical Study Program:**

The SYMON Clinical Study Program includes SYMON-I (clinicaltrials.gov ID NCT06181604), SYMON-II (NCT06654895), and SYMON-III (NCT07425587). SYMON-I is a pilot study to determine IL-6 levels associated with various endpoints, including, but not limited to 28-day all-cause mortality and in-hospital mortality. The SYMON-II study is the pivotal study to validate the outcomes of the SYMON-I study, which the Company plans to use to support a 510(k) application to the FDA. The SYMON-III study is a pilot study to determine IL-6 levels associated with patients presenting with increasing severity of infection in the emergency department and risk of developing sepsis.

Bluejay Diagnostics, Inc. is a medical diagnostics company focused on improving patient outcomes using its Symphony System, a cost-effective, rapid, near-patient testing system for sepsis triage and monitoring of disease progression. Bluejay does not yet have regulatory clearance for the Symphony System, and we will need to receive regulatory authorization from the U.S. Food and Drug Administration before Symphony can be marketed as a diagnostic product in the United States.
