Tampa General Hospital has adopted MeMed BV, an FDA-cleared test that measures a patient’s immune response to help distinguish bacterial from viral infection. The assay produces a result in about 15 minutes. Tampa General integrated it into its EHR–based emergency department sepsis-alert workflow, following an evaluation involving 893 adult emergency department patients from September 2024 through October 2025. The hospital’s announcement describes the evaluation and implementation, but does not establish clinical outcomes from the full rollout.

Sepsis alerts can identify patients who need prompt assessment, but an alert alone does not tell clinicians what is causing an infection. Tampa General’s approach puts another piece of diagnostic information into the workflow where treatment decisions are made. That could help clinicians assess when antibiotics are warranted and support antimicrobial stewardship, provided the result reaches them in time and is interpreted alongside the patient’s condition. The test is an aid to clinical judgment, not a stand-alone sepsis diagnosis.
