How to Commercialize a Medical Diagnostic
Diagnostics are deceptively difficult to commercialize because analytical performance alone does not create adoption. A successful diagnostic must be technically reliable, clinically meaningful, operationally usable, economically justified, and supported by an appropriate regulatory and reimbursement strategy.
1. Define the Intended Use before Perfecting the Assay
The same underlying technology can become very different products depending on population, specimen, setting, user, claim, and clinical decision. Those choices affect validation, regulatory classification, workflow, reimbursement, and market size.
- Who is tested?
- Why are they tested?
- What specimen is used?
- Where is the test performed?
- Who orders and interprets it?
- What clinical action changes because of the result?
2. Separate Analytical Validity from Clinical Value
Analytical performance—accuracy, precision, sensitivity, specificity, interference, reproducibility, stability—is necessary. Commercial adoption also depends on whether the result improves a clinically meaningful decision.
Build evidence around the comparator and outcome that matter to the intended user and payer, not simply the easiest study to publish.
3. Map the FDA Pathway Early
For IVDs, FDA classification and premarket requirements depend on device type and risk. Existing device types may follow 510(k), while a novel low- to moderate-risk device without a predicate may be eligible for De Novo classification. High-risk devices generally require PMA. When classification is uncertain, FDA resources, a Pre-Submission, or a 513(g) request can help clarify the pathway.
4. Build Reimbursement into Product Strategy
A test can be clinically useful and still fail commercially if no stakeholder has a reason to pay for it. Evaluate coding, coverage, payment, health-economic value, site-of-service economics, and who bears the cost versus who receives the benefit.
5. Validate Workflow and Adoption
Talk to laboratory directors, clinicians, administrators, payers, and procurement stakeholders. Understand sample logistics, turnaround time, instrumentation, training, reporting, integration, and the threshold for switching from the current standard.
6. Choose the Commercialization Model
Possible models include centralized testing, distributed kits, instrument-plus-consumable models, licensing, partnerships with established diagnostic companies, or strategic acquisition. The product design should fit the model, not the other way around.
BYB Takeaway
The best diagnostic commercialization plans begin with the clinical decision and work backward to the assay, evidence, regulatory path, reimbursement strategy, and business model.
Do not ask only, 'Does the test work?' Ask, 'What decision does it improve, and who will pay to improve that decision?'
