Bayesian Health vs Cytovale IntelliSep (2026)
Both help clinicians catch sepsis early, one from the record and one from a blood sample. Bayesian Health reads the EHR continuously and flags inpatients at rising risk of sepsis, with order sets and documentation prepared; its sepsis module is FDA cleared. Cytovale's IntelliSep is an FDA cleared blood test for adults with signs of infection in the emergency department. A benchtop analyzer in the hospital laboratory pushes white blood cells from 100 microliters of blood through a microfluidic junction and estimates the probability of sepsis from how the cells deform. They work at different points. Choose IntelliSep for a test at the emergency department door; choose Bayesian to keep watching patients after admission.
- You want continuous surveillance of inpatients after admission.
- Alerts should come with order sets and documentation ready.
- No new laboratory equipment should be needed.
- You want a test at the emergency department door for patients with signs of infection.
- A measured result from a blood sample suits your clinicians better than a record based score.
- Your laboratory can run a benchtop analyzer.

Bayesian Health, a Johns Hopkins spinout founded by Suchi Saria, sells a platform of machine learning models that read the EHR continuously and flag inpatients at rising risk, with workflows that prepare order sets and documentation for clinicians to act on. Its lead module detects sepsis early.

Cytovale makes IntelliSep, an FDA-cleared blood test that estimates the probability of sepsis in adults with signs of infection in the emergency department by measuring how their white blood cells deform. The Cytovale System, a benchtop analyzer in the hospital laboratory, pushes tens of thousands of white cells from 100 microliters of blood through a microfluidic junction and films them; image analysis and a trained model turn the cell measurements into the IntelliSep Index, a score from 0.1 to 10.0 in three bands, in about eight minutes.

Questions buyers ask
How are Bayesian Health and Cytovale IntelliSep priced and sold?
For Bayesian Health, the product is sold to health systems as an enterprise platform, by module, with implementation that tunes models to each site.
The model is a capital instrument, the Cytovale System, plus a single-use cartridge and reagents for each test, with quality control material bought from the company or made by the laboratory. The laboratory page states the footprint and service load: four feet of bench, a one-week installation, no calibration and preventive maintenance every 90 days. From the AI Health Index, drawn from each vendor's own published materials and the regulatory record, verified September 29, 2026. No vendor pays for placement.
How do Bayesian Health and Cytovale IntelliSep handle patient data?
In Bayesian Health's case, the company's privacy policy covers its marketing website. Nothing published states what patient data is retained, for how long, whether one health system's data develops models used by others, or who inside the company can reach identified records.
For Cytovale IntelliSep, the analyzer is a closed benchtop instrument that sends results to the hospital's middleware and laboratory information system. From the AI Health Index, drawn from each vendor's own published materials and the regulatory record, verified September 29, 2026. No vendor pays for placement.
Which settings and specialties do Bayesian Health and Cytovale IntelliSep cover?
With Bayesian Health, the cleared sepsis module covers adults 18 and over from emergency department presentation or admission through the stay in acute care, including observation units, general wards and intensive care, and its evidence spans five hospitals in the outcome study and four in the clearance study, academic, urban and suburban.
In Cytovale IntelliSep's case, the setting is the adult emergency department at the point of triage, for patients with signs and symptoms of infection, with a three-day prediction window. From the AI Health Index, drawn from each vendor's own published materials and the regulatory record, verified September 29, 2026. No vendor pays for placement.
What evidence is published for Bayesian Health and Cytovale IntelliSep?
For Bayesian Health, the company's own clearance study (K250680) adds a retrospective validation on 7,732 encounters at four hospitals.
One hospital's pre and post study (Healthcare, 2025) reported sepsis-associated mortality falling from 10.9 to 6.6 percent after a quality program that included the test, with Cytovale staff helping analyze the data; the design cannot separate the test from the program around it. Company authors or company assistance appear on most of these papers. From the AI Health Index, drawn from each vendor's own published materials and the regulatory record, verified September 29, 2026. No vendor pays for placement.
