Expert-Dx
Expert-Dx is an expert diagnostic consultation app for ordering physicians with hard lab and diagnostic cases, led by Dr. Michael Laposata and built with the 1health team.
Expert-Dx 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.

Founder story
A four-decade dream, built on 1health
Dr. Michael Laposata, founder of Expert-Dx, explains how 1health made expert diagnosis from blood tests possible: cases arrive in a few clicks, without linking electronic health records, and are turned around in minutes.
Dr. Michael Laposata - The Dream
Speakers: Dr. Michael Laposata
Dr. Michael Laposata (0:00): Hi, this is Dr. Mike Laposata and I want to tell you that I've had for more than four decades a dream that allows experts to bring diagnosis to people coming from blood tests, whether they're simple or complicated. But it was cost and technologically prohibitive and really only since the spring after being approached by somebody from 1health, that they could turn the dream into a reality.
And it was a matter of getting the case to me and having me turn around the case in minutes and not hours or days. We built the front door. 1health has support to build incredible software that allowed information to come in with just a few clicks. There was no more trying to link electronic health records.
I wanted to make it understandable to every health care provider seeing a patient from the nurse practitioner on up. This is what makes a national network possible and I am thrilled to be able to bring it to you through expert-dx.com.
The Challenge
The hard thing about Expert-Dx 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 the app does
Expert-Dx 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.
Case Intake
Labs and the clinical picture captured through a simple structured intake — no fax, no portal.
AI-Assisted Synthesis
Relevant results, history, and prior context drafted into a structured picture for the expert.
Expert Review & Signing
A credentialed diagnostic expert reviews, corrects, and signs the final interpretation.
Delivery to Ordering Physician
A clear, signed diagnosis and recommended next steps filed back into the record.
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 a month on proven clinical rails
- A fraction of the cost — the expensive layer already existed
- No engineering team to hire
- 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
Expert-Dx 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 with the 1health team.
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.
