ExpertDx
Direct access to a credentialed diagnostic expert for complex lab and diagnostic cases — an operator on the 1health platform.
ExpertDx gives any ordering physician direct access to a credentialed diagnostic expert for the hardest lab and diagnostic cases. AI does the heavy lifting on synthesis; a real expert signs the final answer back to the physician.
A physician with a proven clinical model should not have to become a software company to use it. That is the part the 1health platform solved.

The Challenge
The hard thing about ExpertDx was never the diagnosis — it was everything wrapped around it. A HIPAA-compliant way to move a case between two organizations that have no relationship. Identity and consent. Licensure routing. An audit trail a hospital compliance office will accept. Billing. A corporate structure that survives a regulatory read. Every one of those is a year of work and a budget, and none of them is medicine.
What ExpertDx built on 1health
ExpertDx did not start from an empty repository. It started from working infrastructure already carrying clinical traffic — the only new work was what is specific to expert diagnostic consultation.
HIPAA-Compliant Case Transfer
Moving a case between organizations with identity, consent, encryption, and an audit trail already in production.
Built on:
Case Intake
Labs and the clinical picture captured through a simple structured intake — no fax, no portal.
Built on:
AI-Assisted Synthesis
Relevant results, history, and prior context drafted into a structured picture for the expert.
Built on:
Expert Review & Signing
A credentialed diagnostic expert reviews, corrects, and signs the final interpretation.
Built on:
Delivery to Ordering Physician
A clear, signed diagnosis and recommended next steps filed back into the record.
Built on:
Billing & Expert Payout
Pricing, unit economics, and the expert payout structure that has to hold as case volume grows.

Transformation
What this normally costs
- ~12 months from decision to a usable product
- $500K–$1M quoted for a HIPAA-compliant clinical app
- Hire a CTO, engineers, compliance, and security review
- Raise a round to fund the build before any demand signal
- Become a software company to use your own clinical model
What actually happened
- Live in about one month on proven clinical rails
- A fraction of the cost — the expensive layer already existed
- No engineering team to hire (the platform built it)
- Real cases moving before the raise, changing what the raise was for
- The expert keeps doing the thing only they can do

Two layers behind the build
ExpertDx went all in on everything. In practice it splits into two layers: the platform, and the company built around it. The next expert takes what they need — some want the full build, some bring their own people and just want the rails.
The platform
Standard with every build. This is what running on the 1health platform means.
HIPAA-compliant healthcare rails
The infrastructure that moves a case between organizations, with identity, consent, encryption, and an audit trail already in place and already in production.
Product and engineering
The case workflow, the AI drafting step, the expert review and signing interface, and the delivery back to the ordering physician, all designed and built on the 1health platform.
Ongoing platform operations
Security, uptime, compliance, and support, run by the platform rather than by a clinical team that should be reading cases.
The company around it
The work each expert decides how much of they want to own.
Regulatory and corporate architecture
Corporate form, state licensure routing, the consultation posture, and the clinical risk structure, worked out before the first case rather than after the first problem.
Business model and economics
Pricing, unit economics, the expert payout structure, and the operating model that has to hold as case volume grows.
Go to market
Positioning, the physician outreach program, the site itself, and the commercial motion behind it.
