FDA-cleared profile

ScreenDx

Imvaria, Inc

ScreenDx provides adjunctive positive/negative assessment of interstitial lung findings on DICOM lung CT in patients older than 22 years to support referral for clinical assessment; it does not rule in or rule out lung fibrosis or replace standard diagnosis.

Evidence status: each field shows source quality, applicability, and review date. Research pending, information not established in reviewed sources, and vendor documentation pending are distinct outcomes.

Clinical fit

What this tool is for

Start with the authorized purpose, then verify how it fits your service line and reading workflow.

Exact purpose
ScreenDx provides adjunctive positive/negative assessment of interstitial lung findings on DICOM lung CT in patients older than 22 years to support referral for clinical assessment; it does not rule in or rule out lung fibrosis or replace standard diagnosis.

Care setting and population
Hospital or clinic referral workflows; eligible patients are older than 22 years.
FDA source Exact FDA submission Checked 2026-09-05
Workflow role
Adjunctive detection supporting referral and clinical assessment.
FDA source Exact FDA submission Checked 2026-09-05
Required input
DICOM-compliant lung CT scans submitted through an image-receiver API; ingestion selects appropriate cases for analysis.
FDA source Exact FDA submission Checked 2026-09-05
Output and human action
Binary Positive (Suggestive of ILD)/Negative result; results are stored and transmitted by an output API to assigned users. No diagnostic information or image localization is generated.
FDA source Exact FDA submission Checked 2026-09-05
Limitations
Not a rule-in or rule-out test for lung fibrosis and not a replacement for current diagnostic methods. Use results with history, symptoms, other diagnostic tests, and professional judgment; age must be greater than 22 years.

Implementation

Questions for IT, informatics, and operations

Use these fields to structure a vendor demo, security review, and implementation estimate.

Integration
Image Receiver API accepts cases from compliant systems such as DICOM/PACS. Output API integrates with hospital/clinic notification software such as an EHR or messaging system; the institution controls the output workflow.
FDA source Exact FDA submission Checked 2026-09-05

Named interface protocols and local vendor-version compatibility are not established by these examples.

Deployment and data flow
Vendor documentation pending
Vendor confirmation Exact FDA submission Checked 2026-09-05

FDA describes APIs and an ingestion/analysis system but does not establish the current customer's hosting topology, region, or retention terms.

Security and privacy
Vendor documentation pending
Vendor confirmation Exact FDA submission Checked 2026-09-05

No dated, scoped commercial security attestation was reviewed. Data transfer, storage, deletion, access control, and incident-response terms remain to be obtained.

Training and support
Vendor documentation pending
Vendor confirmation Exact FDA submission Checked 2026-09-05

The vendor describes background automation, but clinician training and referral-ownership onboarding commitments were not established.

Monitoring and change control
The FDA-cleared PCCP permits defined model-architecture and classification cut-off updates using prescribed data management, retraining, performance evaluation, and update procedures.
FDA source Exact FDA submission Checked 2026-09-05

This establishes the regulatory change-control scope only. Installed model, notification of updates, local acceptance, and production monitoring remain site/vendor questions.

Image and notification APIs

Image-receiver API, ingestion/analysis system, and output API connect image submission with institutional notification workflows.

Evidence

Performance evidence

Metrics are shown only when they are tied to a source, endpoint, population, and tested product version.

Evidence summary
Retrospective multicenter pivotal study of 3,018 unique patients, enriched to 23% positive lung-fibrosis diagnoses, using independently recorded clinical diagnoses as reference. The baseline reports sensitivity 91.4% and specificity 95.2%; an additional 2,482-case low-prevalence dataset is separately described in the FDA summary.

Economics and lifecycle

Budget and ongoing governance

These are common procurement questions; unknown values remain visible until a source supports them.

Pricing and total cost
Vendor documentation pending
Vendor confirmation Exact FDA submission Checked 2026-09-05

The reviewed official ScreenDx page requests contact and does not specify a scoped price. Confirm per-case or enterprise terms, integration, minimum volume, and support; procurement research is incomplete.

Reimbursement and coding
Research pending
Needs research Exact FDA submission Checked 2026-09-05

No applicable payer policy was reviewed; Fibresolve or underlying CT payment cannot establish ScreenDx reimbursement.

Safety and lifecycle

Postmarket record

Recall and adverse-event records are shown only after product matching. Adverse-event reports do not establish incidence or causality.

Postmarket safety review
Not established in reviewed sources
Reviewed sources checked Exact FDA submission Checked 2026-09-04

No native submission-identifier match was found in the checked openFDA radiology recall snapshot. Product-name, manufacturer, and adverse-event searches remain necessary; this does not establish that no recall or safety report exists.
