Too slow
Send-out testing can delay same-visit decisions.
Easy, fast, comprehensive blood testing for better clinical decisions.
Phostronyx is developing FusionDx®, a touch-to-result point-of-care testing platform designed to bring comprehensive blood insights closer to the patient, the clinician, and the moment decisions are made.

Care decisions often move faster than test results.
Central lab tests are accurate but too slow and too far away. Fingerstick tests are fast but too narrow and operator dependent. When blood testing is delayed, incomplete, or inaccessible, clinicians and patients fall back on symptoms, unreliable signals that routinely lead to missed emergencies, misdiagnosis, worse outcomes, and higher costs.
Too inaccessible and fragmented
Sample collection, transfer, testing, and interpretation often happen in separate steps.
Too narrow
Many point-of-care tools solve one slice of the problem, not the full workflow.
Safe to stay home

Symptoms alone create ambiguity
FusionDx is built to separate who's safe from who needs care
Symptoms are ambiguous, decisions shouldn’t.
Symptoms alone can’t reliably tell who needs urgent care. Fast, accessible, and complete tests are essential.
FusionDx® Solution: An integrated, sample‑to‑answer workflow that turns a small blood sample into an actionable result.
The FusionDx® platform unifies the missing pieces: automated sample collection, closed‑cartridge processing, multi‑analyte breadth, and QC‑guided digital interpretation, into one coordinated workflow. Multi layered AI underpins the entire process, powering real time QC, supervised clinical models, longitudinal monitoring, and emerging disease endotype discovery. We’re not replacing the central lab. We’re making the essential diagnostic layer between symptoms and escalation accessible, immediate, and clinically useful.
1
Collect
A small-volume blood sample is collected through a dedicated sampling puck.
2
Dock
The sample is transferred into a closed cartridge workflow.
3
Run
The reader performs controlled measurement and analysis.
4
Act
Results are presented to support timely care decisions.
We believe that high quality diagnosis should be within reach for everyone.
Our founding team came together around a simple belief: everyone deserves fast, accessible, and high quality diagnosis. We’re relentless because the need is urgent, and because every breakthrough brings us closer to our goal. To make that future real, Phostronyx brings together expertise in medical device development and commercialization, electro optical systems, microfluidics, assay integration, software, quality, and clinical workflow design.
